Checking Your Work

Double-Check for Success

One of the best ways to avoid mistakes is to check your answers. After solving an equation or inequality, substitute your answer back into the original problem to make sure it works. This helps catch small errors and builds your confidence.

Why It Matters

Checking your work helps you learn from mistakes and ensures you really understand the steps, not just the answer.

Examples

  • Solve \( x + 4 = 9 \), get \( x = 5 \). Plug back in: \( 5 + 4 = 9 \)

  • For \( 2y = 12 \), \( y = 6 \). Check: \( 2 \times 6 = 12 \)
