Step-by-step explanation:

Step 1: Define

2(x/4 + 8) = 18

Step 2: Solve for x

Divide 2 on both sides:                     x/4 + 8 = 9Subtract 8 on both sides:                  x/4 = 1Multiply 4 on both sides:                   x = 4

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    2(4/4 + 8) = 18(Parenthesis) Divide:           2(1 + 8) = 18(Parenthesis) Add:              2(9) = 18Multiply:                               18 = 18

Here we see that 18 does indeed equal 18.

∴ x = 4 is the solution to the equation.
