Solving a One-Step Linear Equation Problem Type 1

Introduction

In this type of problems, we use either only addition or subtraction operation to move the numbers and get the solution for the one-step equations.

Problem 1

Identify the solution to the linear equation 3 + x = 5

Solution

Step 1:

In this problem, we use subtraction to move the numbers and get the solution for the one-step equation.

3 + x = 5

Step 2:

Subtracting 3 from both sides of the equation to isolate the variable x.

3 + x 3 = 5 3

So, x = 8

Problem 2

Identify the solutions to the linear equation 11 y = 8

Solution

Step 1:

In this problem, we use addition to move the numbers and get the solution for the one-step equation.

11 y = 8

Step 2:

Adding 11 to both sides of the equation to isolate the variable y.

11 y + 11 = 8 + 11

y = 19

Step 3:

Changing sign on both sides of the equation

So, y = 19
