One Step Equations
One step equations are algebraic equations that can be solved in one step only. Such equations can be solved in just one step by adding, subtracting, multiplying, or dividing. To solve onestep equations, we apply the inverse of the fundamental operation of whatever operation is already applied to the variable. For example, if a constant is added to the variable, we subtract it to solve the onestep equation.
This article will discuss the concept of onestep equations and we will learn how to solve them stepwise. We shall solve various examples to understand the method of solving one step equations in a better way.

What are One Step Equations?
One step equations are algebraic equations that can be solved in just one step. We determine the value of the variable involved to solve such equations. We can linear, quadratic, as well as cubic onestep equations. We have different types of one step equations depending upon the types of coefficients and constant terms involved such as:
Some of the examples of one step equations are:
 2x = 7
 y  7 = 6
 x^{2} = 16
 a^{3} = 8
 x/5 = 10
 4 + y = 9
Steps to Solve OneStep Equations
Now that we have understood the meaning of one step equations, let us go through the process of solving onestep equations stepwise. The inverse operations pairwise are addition and subtraction, and division and multiplication. Given below are the steps that help us in solving one step equations:
 Step 1: Understand and evaluate the one step equation.
 Step 2: Determine the operation applied to the variable.
 Step 3: Identify the inverse operation of the operation applied to the variable.
 Step 4: If the variable is multiplied by a number, divide both sides of the equation by the same number to isolate the variable. (If the variable is divided by a number, multiply both sides of the equation by the same number.)
 Step 5: If a number is added to the variable, then subtract the same number from both sides of the equation to isolate the variable. (If a number is subtracted from the variable, then add the same number to both sides of the equation to isolate the variable.)
Solving One Step Equations
In the above section, we went through the steps to solve one step equations. Let us now solve a few examples to understand the application of the given steps to solve onestep equations. We will consider equations where different operations are applied to the variable to understand the concept in a better way.
Example 1: Solve one step equation x  7 = 10.
Solution: We have the equation x  7 = 10. Since 7 is subtracted from the variable x, we will add (inverse of subtraction) 7 to both sides of the equation.
x  7 + 7 = 10 + 7
⇒ x = 17
Example 2: Find the value of the variable: 4x = 16.
Solution: The one step equation is 4x = 16. Since 4 is multiplied by the variable x, we divide (inverse of multiplication) both sides of the equation by 4.
4x ÷ 4 = 16 ÷ 4
⇒ x = 4
Example 3: Solve the one step quadratic equation x^{2} = 36.
Solution: We have x^{2} = 36. Taking square root on both sides of the equation, we have
x = 6, 6

Example 1: Solve the equation 4x/7 = 7/9.
Solution: The given equation 4x/7 = 7/9 is a onestep equation with fractions. To solve this, since the variable x is multiplied by 4/7, we divide both sides of the equation by 4/7.
(4x/7) ÷ (4/7) = (7/9) ÷ (4/7)
⇒ x = 49/36
Answer: x = 49/36

Example 2: Find the solution of one step equation x + 9 = 8
Solution: Since 9 is added to the variable x, we subtract (inverse of addition) 9 from both sides of the equation. So, we have
x + 9  9 = 8  9
⇒ x = 1
Answer: x = 1

Example 3: Solve the one step equation y/7 = 2.
Solution: Since the variable y is divided by 7, we multiply (inverse of divide) both sides of the equation by 7.
y/7 × 7 = 2 × 7
⇒ y = 14
Answer: y = 14
