# Whats wrong with these inequalities... watch

1. 9x - 34 < 8 - 5x < 3x + 24

9x - 42 < -5x < 3x + 16
6x -42 < -8x < 16
-42 < -14x < 16
3 > x > -1.14

6x + 6 < 9x + 27

6 < 3x + 27
-21 < 3x
-7 < x

Where have i gone wrong...?
2. Right, for the first one, you have neglected to subtract 6x from the right side of the inequality in the third step.
3. Brook's right, thats your only problem.. the second one is fine.
