And inequalities
Printable practice with an answer key the engine computes, at three levels, in as many versions as you need.
Problem types
- a < x + b < c (one move on all three parts): −2 < x + 3 < 5
- a < bx + c < d (two moves on all three parts): 1 < 2x − 3 ≤ 9
- two inequalities joined by "and": x + 1 > 2 and x − 3 < 1
- a < −bx + c < d (divide by a negative: both symbols turn): −6 < −2x ≤ 4

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.
