How To Solve Simple Equations (With Examples)

What is a simple equation?

Equations are at the heart of almost every field in science and mathematics, from the most basic addition and subtraction problems to the most intricate equations used to solve complex problems. Equations serve as the cornerstone for problem solving and are a powerful tool for understanding the world around us. In the past, equations have been the bane of many students in mathematics but, with the right approach and mindset, equations can be simple, straightforward and even enjoyable. In this blog post, we will explore some of the simple equations that can be used to solve everyday problems. We will look at how to approach simple equations, how to utilize them to solve common problems and how to recognize when to use them in a variety of different scenarios. With this knowledge, we can empower ourselves to work through equations with confidence, no matter the situation.

Algebra Basics: Solving Basic Equations Part 1 – Math Antics

Types of simple equations

You may run into a variety of mathematical equations, from straightforward ones to more difficult ones. However, most simple equations fall into several categories:

Linear equations

The most frequent type of simple equation is a linear equation, which typically has one or more terms on either side of an equal sign. A fundamental algebraic step is the use of linear equations to describe the motion of geometrical lines and segments. Additionally, linear equations can be combined to create quadratic and trigonometric functions as mathematics becomes more difficult, such as in calculus and trigonometry. Additionally, linear equations can be as straightforward as an arithmetic problem like 3 + 4 = 7 or as challenging as solving equations of lines like 3x + y = 12.

Exponential equations

Depending on the type of problem you’re solving, exponential equations sometimes include variables in addition to numerical terms and exponents. Exponents work by multiplying their coefficients by the exponent’s number of times repeatedly. For instance, the exponent of three instructs you to repeatedly multiply seven by itself in the exponential equation of 73 = 147, so 73 = 7 x 7 x 7 = 147.

An exponential equation might contain variables, just like linear equations do. One numerical term and one variable are added together in the equation 62 + b = 40 to create a straightforward exponential equation.

Rational equations

Simple equations with at least one fraction are referred to as rational equations. These straightforward equations can also have multiple operations and require multiple steps to be solved. For instance, all fractions are included in the straightforward equation 3/8 + 1/8 = 1/2 using only the addition operation.

As mathematical topics become more complex, rational equations can also get more complicated. Multiple terms with one or more operations to solve in the numerator or denominator may appear in some rational equations. A rational equation may also contain variables and require one or more steps to solve.

Radical equations

Simple equations with radicals or square root signs are known as radical equations. Depending on the index that appears inside the radical sign, you can either take the square root of a number or a multiple root in a radical equation. You can solve a radical equation by taking the square or cube root of a number, or you can see multiple radical terms that call for multiple operations. Radical equations can have variables, just like the other kinds of simple equations.

What are simple equations?

The relationship between two terms on either side of an equal sign is represented by a straightforward equation. Additionally, basic equations incorporate one or more of the four basic operations of addition, subtraction, multiplication, and division. Simple equations can grow larger with more terms and variables as mathematics becomes more difficult. However, you calculate a problem containing one or a few numerical terms in the majority of simple equations.

For instance, the equation 3 x 4 = 12 has single terms that are denoted by equal and operation signs. 5 + 11 – 2 = 14, which has multiple terms split between two operation signs and the equal sign, is another illustration of a straightforward equation. A straightforward equation, like 5 + a = 10, may also contain a combination of numerical and variable terms. In this instance, the variable denotes an unidentified value that, when added to five, yields a sum of 10, or 10.

Uses for simple equations

Depending on your field, you might encounter simple equations every day. Here are some industries that commonly use simple equations:

Scientific and statistical research

Professionals can approach and overcome challenges in the scientific and statistical fields of study using straightforward equations. For instance, to determine demographic totals, percentages, and ratios, census workers may use straightforward equations. To solve issues involving population studies, statisticians can use linear algebra and statistical analysis. Studies in physics, biology, chemistry, astronomy, and other scientific fields can also use straightforward equations.

Finance and accounting practices

Simple equations are used by financial experts like bookkeepers, accountants, and analysts to calculate financial applications. Accounting professionals may use specific algebraic formulas in corporate finance, for instance, to determine crucial financial data like a company’s revenue, profits and losses, tax liabilities, and return on investments. Businesses and organizations use simple linear equations in mathematics to calculate and record data that can be used to plan and develop budgets, finance activities, and invest.

Education and teaching

You can also find simple equations is in academics. Math curriculum often advances in higher grades. For instance, simple equations at the elementary level consist of the four fundamental operations and numerical values, whereas equations in more complex math, such as algebra and trigonometry, include more complicated terms and variables. Many equational concepts may be taught by teachers in all grades and at the post-secondary levels.

Technology and medicine

There are additional fields where simple and complex equations are used in the technology and medical industries. Professionals in the technical fields of information technology, computer science, computer engineering, software engineering, and cybersecurity frequently use mathematical equations to program, code, and create technical applications.

Medical professionals also rely on simple equations. To measure and administer medications and medical components, professionals in the pharmaceutical industry use mathematical formulas and equations. Simple equations are used by medical technicians, nurses, doctors, and surgeons to measure crucial metrics like vital signs and dosages of medications.

Manufacturing and construction

To operate machinery, design products, and program machines for production, the manufacturing sector uses mathematical equations. To maintain and operate complex machinery during production processes, manufacturing companies frequently employ experts with mathematical skills.

Geometric formulas and linear equations are used by professionals in the construction industry, such as architects, building designers, and engineers, to design, plan, and implement structural blueprints.


Examine the following examples for more information on using simple equations in math:

Linear equation examples

Linear equations can have straightforward issues or more complicated components, depending on the level of mathematics. The following examples illustrate several types of linear equations:

(4 + 12) + 2 = 8
