# I get a solution of #y=3# but how to solve for this limit?? #lim(x->-4)(3x+12)/(x+4)#

This is an indeterminate form that tells us nothing, so we need to simplify.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
