b 64-x=18+12 x+20

Step 1 ：The given equation is \(64 - x = 18 + 12x + 20\).

Step 2 ：To solve for x, we need to simplify the equation and isolate x on one side of the equation.

Step 3 ：Solving the equation gives us the solution x = 2.

Step 4 ：This means that when x = 2, both sides of the equation are equal.

Step 5 ：Final Answer: \(\boxed{2}\)
