1) You have the absolute value of some expression equal to a negative number. This can never happen, since absolute values only give back non-negative answers. So there's no solution.
2) Ditto

1) I3x + 2I = - 8
|3x+2| is always positive and can never = -8. No solution
2) I3x + 2I < - 8
|3x+2| is always positive and can never < -8. No solution
3) I3x + 2I ⥠- 8
True for all x

1. no solution since no absolute value is negative.
2. no solution since no absolute value is less than -8
3. x is greater than or equal to -3.3

-3x-2=-8
-3x-2< 8
-3x-2>8
Absolute value is 0 . to make it zero you have to change the sign in front of the number , + to - and vis versa.
