Variables on Both Sides

Visual 5x + 6 = 3x + 12

Solve 7n – 2 = 5n + 6. Solving Equations with Variables on Both Sides 1: Move variable to one side 7n – 2 = 5n + 6 –5n 2n – 2 = 6 3: multiply/divide 2n = n = 4 2: Add/subtract

1) Solve. 3x + 2 = 4x - 1 You need to get the variables on one side of the equation. It does not matter which variable you move. Try to move the one that will keep your variable positive.

Solve the equation. Check your answer. 4b + 2 = 3b

8y - 9 = -3y + 2

y = 0.7y – 0.3 Solve the equation. Check your answer.

1) 4a – 3 = 2a + 7 2) -3r + 9 = -4r + 5 3) 3d + 8 = 2d – 17 4) 2x – 7 = 5x – 10
