Backsolving Answer Choices

Work Backwards to Save Time

Instead of solving a problem from scratch, try plugging the answer choices into the equation or scenario to see which one works. Start with the middle choice to be efficient.

When to Use

  • Problems with numerical answer choices.
  • Word problems with hidden equations.

Why It Works

This method can be quicker, especially if the question is complex or the algebra is tough.

Pro Tips

  • Eliminate obviously wrong choices first.
  • If the middle choice is too high or low, you know which direction to go.

Examples

  • Testing each answer in the equation \( 3x + 2 = 11 \) to see which value of \( x \) works.

  • Plugging answer choices into a geometry formula to find the correct length.
