Solving Equations (1)
In this section, you will learn how to solve two-step equations and three-step equations -- type 1 and type 2.
When solving equations of this form, we must carefully simplify the equation using a special two-step order. The term that is either adding to or subtracting from the variable must be canceled first by doing the opposite, otherwise known as the inverse operation. For instance given the equation
3x - 5 = -26, the subtraction by five must be cancelled by doing the opposite. We must add five to both sides. Doing so we get,
