Solving Equations with Multiple Steps 2. General Procedure to Solve a Linear Equation 1. Solving Equations with Multiple Steps In Sections 3.2 and 3.3 we studied a one-step process to solve linear equations.We used the addition, subtraction, multiplication, and division properties of equality. In this section, we combine these properties to solve equations that require multiple steps. This is shown in Example 1.
