Find out X
Answer:
x = 6/9
Step-by-step explanation:
9x - 2(x+8) = 5x - 11(2-x)
9x - 2x - 16 = 5x -22 + 11x
collect the like terms
7x - 16 = 5x -22 + 11x
7x-5x = -22 +16 + 11x
2x = -6 + 11x
6 = 11x - 2x
6 = 9x
divide both sides by 9
6/9 = x
I think it's twelve but you best check another answer, im pretty st*pid.
