Solve .
Hint
-48 < x + 2 < 48
Answer
-50 < x < 46
Solve -3 < |-4x + 9|.
This can be rearranged to be |-4x + 9| > -3.
All real numbers are a solution to this inequality.
Solve |3x + 7| > 1.
3x + 7 > 1 or 3x + 7 < -1
Solve 4 – |6x + 6| ≤ -14
Don't jump to conclusions just because of the -14. Clear out the 4 and the minus sign before trying to solve this inequality.
x ≤ -4 or x ≥ 2
|2x – 1| ≤ 7
-7 ≤ 2x – 1 ≤ 7
-3 ≤ x ≤ 4
