Solving Equations
-132 = 4x – 5(6x – 10)
-132 = 4x – 30x + 50 -132 = -26x + 50
-182 = -26x 7 = x
-6x + 2(-4x – 17) = 78
-6x – 8x – 34 = 78-14x – 34 = 78
-14x = 112x = -8
-98 = -7x – 4(2x – 13)
-98 = -7x – 8x + 52-98 = -15x + 52
-150 = -15x 10 = x
5x – 2(-2x – 17) = 124
5x + 4x + 34 = 1249x + 34 = 124
9x = 90x = 10
26 = -7x – 4(2x – 13)
26 = -7x -8x + 5226 = -15x + 52
-26 = -15x 1.73 = x
4x + 4(-6x – 6) = -144
4x – 24x – 24 = -144-20x – 24 = -144
-20x = -120x = 6
137 = -5x + 4(5x +8)
137 = -5x + 20x + 32137 = 15x + 32
105 = 15x7 = x
186 = 6x – 4(7x – 8)
186 = 6x – 28x + 32186 = -22x + 32
154 = - 22x-7 = x
