.

Divide both sides by 3.


You will get an equivalent inequality


|u+5| > 4.


The solutions are those values of "u" that are remoted more than 4 units from -5, i.e.  u < -9   and/or  u > -1.


Answer.  The solutions are these two intervals  u < -9  and  u > -1.


         In the interval notation, the solution is the union of these two intervals:  (,) U (,).
