Step-by-step explanation:

Step 1: Define

6x + 6 = -10 + 8x

Step 2: Solve for x

1. [Subtraction Property of Equality] Subtract 6x on both sides:                    6 = -10 + 2x
2. [Addition Property of Equality] Add 10 on both sides:                                  16 = 2x
3. [Division Property of Equality] Divide 2 on both sides:                               8 = x
4. Rearrange/Rewrite:                                                                                        x = 8

Step 3: Check

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

1. Substitute in x:                                                                                                6(8) + 6 = -10 + 8(8)
2. Multiply:                                                                                                           48 + 6 = -10 + 64
3. Add:                                                                                                                 54 = -10 + 64
4. Add:                                                                                                                54 = 54

Here we see that 54 does indeed equal 54.

∴ x = 8 is the solution to the equation.
