What is the solution to the equation 9x = 72?

Explanation:
When solving a simple equation like 9x = 72, you undo the multiplication by 9 on x. Divide both sides by 9 to isolate x. 72 ÷ 9 equals 8, so x is 8. You can check by multiplying back: 9 × 8 = 72, which matches the right side. If you tried the other values, you’d get 9 × 6 = 54, 9 × 9 = 81, or 9 × 12 = 108, none of which equal 72. So the solution is 8.
