What is the solution to the compound inequality 1 < 2x + 3 < 7?

Back

Subtract 3 from all parts: -2 < 2x < 4. Then divide by 2: -1 < x < 2.

Front

What is the difference between a strict inequality and a non-strict inequality?

Back

A strict inequality (< or >) does not include the endpoint, while a non-strict inequality (≤ or ≥) does include the endpoint.

How do you solve the inequality -3(x - 2) < 6?

Back

Distribute -3: -3x + 6 < 6. Then subtract 6: -3x < 0. Finally, divide by -3: x > 0.
