2 > - | (x - 8) / 5 + 3/5 |
- | (x - 8) / 5 + 3/5 | < 2
| (x - 8) / 5 + 3/5 | > -2
Since an absolute value is always at least zero, there is no value of x that won't work.
The solution is "all real numbers".
5 < | (3k -1) / 4 |
| (3k -1) / 4 | > 5
Either: -5 < (3k -1) / 4 or (3k -1) / 4 > 5
-20 < 3k - 1 3k - 1 > 20
-19 < 3k 3k > 21
-19/3 < k or k > 7
