To solve the equation 7x - 7 = 2x + 8:

- First, isolate the terms with x on one side of the equation. Subtract 2x from both sides: 7x - 2x - 7 = 8
- Simplify the left side of the equation: 5x - 7 = 8
- Next, add 7 to both sides of the equation to isolate the term with x: 5x = 15
- Finally, divide both sides by 5 to solve for x: x = 3

Therefore, the solution to the equation is x = 3.
