X - 5 + 12 + 2x = 4 (8 - 11x) + 7 (1 + 9x)

Isolate the variable by dividing each side by factors that don't contain the variable. x = - 2

x = - 2

Step-by-step explanation:

x - 5 + 12 + 2x = 4 (8 - 11x) + 7 (1 + 9x)

x - 5 + 12 + 2x = 32 - 44x + 7 + 63x

x - 5 + 12 + 2x = 32 - 44x + 7 + 63x

x + 2x + 44x - 63x = 32 + 7 + 5 - 12

- 16x = 32

- x = 32 / 16

- x = 2

x = - 2
