Chapter 3: Solving Linear Equations
Solving Equations: One, Two, Mult- Steps One-Step: 4w = 48 Divide both sides by four w = 12

Two-Step: 2m - 13 = 15 +13 +13 2m = 28 Divide both sides by two m = 14

Multi-Step:

3t + 5t -5 =11 Add the like terms 8t - 5 = 11 +5 +5 8t = 16 Divide both sides by eight t = 2

Solving Equations with Variables on Both sides x + 3 = 2x -x -x 3 = x

Ratios and Proportions The cross products of proportions are equal.
