Essential Question: Why do we use inverse operations when solving an equation?
Provide the inverse of each operation.
A 1-step equation is an equation that involves one operation. In order to solve the equation, you must use the inverse operation, or do the opposite of the operation in the equation. For example, the inverse of addition is subtraction. When you undo the operations by using the inverse, you will isolate the variable to get it by itself on one side of the equation. When you perform the inverse operation on one side of the equation, you must do it to the other side so both sides remain balanced and equal.
