See below.

Explanation:

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!
