Variables on Both Sides with Equations Objective – SWBAT solve equations with variables on both sides.

How do you solve an equation with variables on both sides? Step 1 – Add or subtract the variable from one side of the equal sign to the other side of the equal sign Step 2 – Follow the one-step or two-step equation rules

Practice Problems 1. 4x = 2x + 10 -2x -2x 2x = 10 2 2 x = 5 3. 8x – 5 = 3x + 5 -3x -3x 5x – 5 = 5 +5 +5 5x = 10 5 5 x = 2 2. -4x – 18 = 5x +4x +4x -18 = 9x 9 9 x = -2 4. x + 10 = 6x - 45 -6x -6x -5x + 10 = -45 -10 -10 -5x = -55 -5 -5 x = 11
