You have to isolate the absolute value first and then split the equation. Sometimes it won't work. Like for instance the first one. |3x+4| +3 <_ 2 Subtract 3 from both sides. |3x+4| <_-1 Well an absolute value can never be less than -1, so no answer.

First multiply each side by 4 and get: |4x + 12| < 4(1/2) = 2 That is |4x+12| <2 Now add 1 to both side and get: |4x +13| < 3 OK!
