See below.

The first step that we want to do is add #5# to both sides of the equation, as we want to combine the numbers:

#-2x-5=77#

#-2x=82#

Now, we can divide by #-2# on both sides in order to eliminate the coefficient in front of #x# (the number in front of #x#, which is #-2#):

#-2x=82#

#x=-41#

This is our solution, #x=-41#!

I hope that helps!
