No solution - See below

Explanation:

#3abs(x+2) <0#

The absolute function returns a positive or zero value for all arguments. Hence, it should be obvious the no value of x can satisfy this inequality.

To show this graphically, consider the graph of #f(x) = 3abs(x+2)# below.

graph{3abs(x+2) [-10, 10, -5, 5]}

#f(x) >=0 forall x in RR#
