How to solve

Inequalities are solved like equations — apply inverse operations to isolate the variable — but the inequality direction is part of the answer. Multiplying or dividing by a negative flips the inequality; these drills avoid that case so the focus stays on isolation.

Steps

  1. Use inverse operations on both sides, just as with an equation.
  2. Keep the inequality symbol unless you multiply or divide by a negative (not needed here).
  3. Write the solution with the variable on the left when possible.

Example

Solve x + 4 > 9.

  1. Subtract 4 from both sides: x > 5.

Answer: x > 5

How to type answers

  • Enter like x > 3 or x <= -2 (use <= and >=)
