Two-step inequalities
Printable practice with an answer key the engine computes, at three levels, in as many versions as you need.
Problem types
- ax ± b < c, a positive: 3x + 4 < 19
- b + ax < c (the constant comes first): 4 + 3x < 19
- ax ± b < c, a negative (flip): −2x + 5 ≥ 11
- b − ax < c (the constant comes first, flip): 5 − 2x ≥ 11
- x/a ± b < c, a positive: x/3 + 4 > 9
- x/a ± b < c, a negative (flip): x/(−3) + 4 > 9
Sample Sheet · Level 1
- −3x − 2 ≥ 10
- 2x + 3 ≤ 11
- −6 + 4x ≥ −14
- x5 + 9 < 12
- −6x − 9 ≤ −3
- 4x − 2 > 6
- 1 ≤ 3 + x3
- −17 ≥ 4 + 3x
Answer key
- x ≤ −4

- x9 − 5 > 2
- −22 + 2x < 18
- x5 + 20 > 11
- −10 + x−6 ≤ −3
- 15 ≥ −2x + 2
Answer key
- x ≥ 253 = 813

Make your own
Pick the count, the level and the version, and print it with work space and the key on its own page. The same skill also makes an I Do, We Do, You Do lesson, a Mosaic, a Decoder and more.
