Step-by-step explanation:

Step 1: Define equation

38 + 7x = 8(x + 4)

Step 2: Solve for x

Distribute 8:                              38 + 7x = 8x + 32Subtract 7x on both sides:       38 = x + 32Subtract 32 on both sides:      6 = xRewrite:                                     x = 6

Step 3: Check

Plug in x to verify it's a solution.

Substitute:                    38 + 7(6) = 8(6 + 4)Add:                              38 + 7(6) = 8(10)Multiply:                        38 + 42 = 80Add:                              80 = 80

Here, 80 does indeed equal to 80. ∴ x = 6 is a solution.

And we have our final answer!
