Solving Multi-Step Equations September 8, 2015

Steps for Solving…. 1. Simplify one or both sides of the equation (if needed). You may need to distribute or combine like terms. 2. Use inverse operations to isolate the variable. (DO THE OPPOSITE OF ORDER OF OPERATIONS) a. UNDO ADDITION OR SUBTRACTION b. UNDO MULTIPLICATION OR DIVISION

Solving a Linear Equation Write the original equation. Subtraction property of equality. Simplify. Multiplication property of equality. Simplify. CHECK 3 3

Combining Like Terms First… Write the original equation. Combine like terms. Addition Property of Equality. Simplify. CHECK Division Property of Equality 4 4
