Checking Your Work

Always Double-Check

After solving a problem, plug your answer back into the equation to make sure it works. This simple habit catches mistakes and boosts your confidence. Even experts double-check their answers!

Examples

  • If you solve \( x + 4 = 9 \) and get \( x = 5 \), check by seeing if \( 5 + 4 = 9 \).

  • Review your graph to make sure it matches your equation.
