Explanation:
Step 1: Define
6x + 6 = -10 + 8x
Step 2: Solve for x
- [Subtraction Property of Equality] Subtract 6x on both sides: 6 = -10 + 2x
- [Addition Property of Equality] Add 10 on both sides: 16 = 2x
- [Division Property of Equality] Divide 2 on both sides: 8 = x
- Rearrange/Rewrite: x = 8
Step 3: Check
Plug in x into the original equation to verify it's a solution.
- Substitute in x: 6(8) + 6 = -10 + 8(8)
- Multiply: 48 + 6 = -10 + 64
- Add: 54 = -10 + 64
- Add: 54 = 54
Here we see that 54 does indeed equal 54.
∴ x = 8 is the solution to the equation.
