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