Let's look at some examples of solving one-step equations.

Whenever you solve a word problem involving a one-step equation you are finding the value of the variable.

The key to solving one-step equations with addition and subtraction is, whatever operation you perform on one side of the equation, you must also perform on the other side of the equation.

In order to isolate your variable, you perform an "Inverse Operation" which means if you have subtraction the inverse operation is addition.
