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
- Use inverse operations on both sides, just as with an equation.
- Keep the inequality symbol unless you multiply or divide by a negative (not needed here).
- Write the solution with the variable on the left when possible.
Example
Solve x + 4 > 9.
- Subtract 4 from both sides: x > 5.
Answer: x > 5
How to type answers
- Enter like x > 3 or x <= -2 (use <= and >=)
