You can put this solution on YOUR website! 3-*absolutevaluesign* 2(x-5)+12 *absolutevaluesign* < 4
-------------------
3 - |2(x-5)+12| < 4
----
|2(x-5)+12| > -1
-------------------------------
Since an "absolute value" is never negative,
the inequality is true for all values of "x".
Ans: All Real Numbers.
