How do you solve the inequality 15 > -5 + z?

Back

To solve, add 5 to both sides: 20 > z or z < 20.

Front

How do you solve the inequality x + 5 > 7?

Back

To solve, subtract 5 from both sides: x > 2.

Front

How do you solve the inequality -8x < 48?

Back

To solve, divide both sides by -8 (remember to flip the inequality): x > -6.

Front

What does it mean to 'flip' the inequality symbol?

Back

Flipping the inequality symbol occurs when you multiply or divide both sides of an inequality by a negative number.
