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.
