Or inequalities
Printable practice with an answer key the engine computes, at three levels, in as many versions as you need.
Problem types
- two inequalities joined by "or": x − 1 < −3 or 2x > 6
- a negative coefficient in one part (flip): −2x > 6 or x + 1 ≥ 5
- the two rays overlap: all real numbers: x > 2 or x < 5
Sample Sheet · Level 1
- 2x < 4 or 3x > 9
- 2x < 2 or x − 7 ≥ −1
- x − 3 < −1 or 4x > 32
- x + 8 ≥ 14 or 4x ≤ 4
- x + 6 ≥ 3 or 4x < −24
- 3x < 12 or 2x ≥ 10
- x + 9 < 6 or 4x ≥ 4
- x − 6 ≥ −3 or 5x < 5
Answer key
- x < 2 or x > 3
- x < 1 or x ≥ 6
- x < 2 or x > 8
- x ≤ 1 or x ≥ 6
- x < −6 or x ≥ −3
- x < 4 or x ≥ 5
- x < −3 or x ≥ 1
- x < 1 or x ≥ 3
Sample Sheet · Level 3
- −3x ≤ 3 or x − 4 < −8
- 4x ≤ −22 or −2x ≤ −16
- 4x > 5 or x − 1 ≤ 2
- 5x > 20 or x − 9 < −7
- 5x > 25 or 2x < −7
- x + 7 < 1 or 4x > 4
- x − 4 ≥ 3 or 2x ≤ 7
- −2x < −17 or 2x ≤ 13
Answer key
- x < −4 or x ≥ −1
- x ≤ −112 or x ≥ 8
- all real numbers
- x < 2 or x > 4
- x < −72 or x > 5
- x < −6 or x > 1
- x ≤ 72 or x ≥ 7
- x ≤ 132 or x > 172
