1. Solving Equations

2. -132 = 4x – 5(6x – 10) -132 = 4x – 30x + 50 -132 = -26x + 50 -182 = -26x 7 = x

3. -6x + 2(-4x – 17) = 78 -6x – 8x – 34 = 78 -14x – 34 = 78 -14x = 112 x = -8

4. -98 = -7x – 4(2x – 13) -98 = -7x – 8x + 52 -98 = -15x + 52 -150 = -15x 10 = x

5. 5x – 2(-2x – 17) = 124 5x + 4x + 34 = 124 9x + 34 = 124 9x = 90 x = 10

6. 26 = -7x – 4(2x – 13) 26 = -7x -8x + 52 26 = -15x + 52 -26 = -15x 1.73 = x

7. 4x + 4(-6x – 6) = -144 4x – 24x – 24 = -144 -20x – 24 = -144 -20x = -120 x = 6

8. 137 = -5x + 4(5x +8) 137 = -5x + 20x + 32 137 = 15x + 32 105 = 15x 7 = x

9. 186 = 6x – 4(7x – 8) 186 = 6x – 28x + 32 186 = -22x + 32 154 = - 22x -7 = x
