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

Mathematics
1 answer:
suter [353]3 years ago

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

<u>Step-by-step explanation:</u>

9x + 2a = ac - bx

9x         = ac - bx - 2a    <em>subtracted 2a from both sides</em>

9x + bx = ac - 2a           <em>added bx to both sides</em>

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

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