How do you solve the inequality 5n + 3 < 18?

Back

Subtract 3 from both sides: 5n < 15. Then divide by 5: n < 3.

Front

What is the first step in solving the inequality 2x - 4 ≥ 10?

Back

Add 4 to both sides: 2x ≥ 14.

Front

How do you graph the inequality x > 2?

Back

Draw a number line, place an open dot at 2, and shade to the right.

Front

How do you graph the inequality x ≤ 5?

Back

Draw a number line, place a closed dot at 5, and shade to the left.

What is the solution to the inequality 3x + 2 < 11?

Back

Subtract 2 from both sides: 3x < 9. Then divide by 3: x < 3.
