Solving Equations

-132 = 4x – 5(6x – 10) -132 = 4x – 30x = -26x = -26x 7 = x

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

-98 = -7x – 4(2x – 13) -98 = -7x – 8x = -15x = -15x 10 = x

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

26 = -7x – 4(2x – 13) 26 = -7x -8x = -15x = -15x 1.73 = x

4x + 4(-6x – 6) = x – 24x – 24 = x – 24 = x = -120 x = 6

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

186 = 6x – 4(7x – 8) 186 = 6x – 28x = -22x = - 22x -7 = x
