18%28x-9%29%2B81=18x-9%2818-x%29 Start with the given equation.


18x-162%2B81=18x-162%2B9x Distribute.


18x-81=18x-162%2B9x Combine like terms on the left side.


18x-81=27x-162 Combine like terms on the right side.


18x=27x-162%2B81 Add 81 to both sides.


18x-27x=-162%2B81 Subtract 27x from both sides.


-9x=-162%2B81 Combine like terms on the left side.


-9x=-81 Combine like terms on the right side.


x=%28-81%29%2F%28-9%29 Divide both sides by -9 to isolate x.


x=9 Reduce.
