Question

If 9x + 2a =ac - bx, then x equals

Answer 1

Answer: $x=\bold{\dfrac{a(c-2)}{9+b}}$

Step-by-step explanation:

9x + 2a = ac - bx

9x         = ac - bx - 2a    subtracted 2a from both sides

9x + bx = ac - 2a           added bx to both sides

x(9 + b) = a(c - 2)           factored out x from the left and a from the right

  $x=\large\boxed{\dfrac{a(c-2)}{9+b}}$          divided both sides by 9+b
