Answer:
The goal of solving two-step equations is to isolate the variable (get it by itself) and solve for the value using the following steps:
1. Add or subtract the constant term from both sides of the equation.
2. Multiply or divide the coefficient from both sides of the equation.
Step-by-step explanation:
Solving equations means using inverse (opposite) operations.
subtraction - addition
multiplication - division
In order to get the variable by itself, you need to first get rid of the constant (the number by itself) by adding or subtracting from both sides of the equal sign. Then, you multiply or divide by the coefficient of the variable to solve for the variable.
