Solve like equations — but flip the sign when you multiply or divide by a negative.

Step 1 · Learn

Walkthrough

Read this first — it covers the idea in plain language with a worked example.

Use inverse operations to isolate the variable, just like with equations.

Flip the sign

When you multiply or divide both sides by a negative number, reverse the inequality symbol.

Worked example

Solve -2x + 1 < 9.

Step 2 · Watch
