Solve for x: x + 7 = 15.

Explanation:
To find x, undo the addition by subtracting 7 from both sides. On the left, x + 7 becomes x. On the right, 15 − 7 is 8. So x = 8. Check: 8 + 7 = 15, which matches the original equation. If you try other values like 7, 9, or 6, you’d get results that aren’t 15, so they don’t work.
