How do you solve the inequality 7x - 3 > 18?

Back

Add 3 to both sides: 7x > 21. Then divide by 7: x > 3.

How do you solve the inequality 12x - 7 ≥ 53?

Back

Add 7 to both sides: 12x ≥ 60. Then divide by 12: x ≥ 5.

How do you solve the inequality 2x + 5 > 12?

Back

Subtract 5 from both sides: 2x > 7. Then divide by 2: x > 3.5.
