#y<-6#

Explanation:

Begin by adding #13# to both sides:

#5+13 < cancel(-13+13)-3y#

Then isolate #y# by dividing by #-3# to both sides

#18/-3 < cancel(-3)/cancel(-3)y#

We change the inequality sign since we divided by a negative:

#-6>y#

However, we want to rewrite the above so that the variable is on the left side instead of the right because it is easier to understand. By doing so, the inequality sign changes once again.

#y<-6#
