Solving inequalities

Same moves as equations — except multiplying by a negative flips the sign.

Solve inequalities the same way as equations — except multiplying or dividing by a negative flips the sign.

Try it

−2x > 6

Divide by −2 and flip: x < −3.

Multiplying by a negative is the only move that flips ≤ to ≥. Don't forget!
