Set the equation equal to 0:
-7x - 7 = 0
Isolate terms:
-7x = 7
Divide the -7 through:
x = -1

Set the equation to 0:
-7x-7=0
-7x=7
x=-1
Check:
-7(-1)-7=0
7-7=0
0=0

Yup. You forgot to set it equal to something. You can't solve it like that because it's not an equation, unless it's a function then you just plug in numbers.
You can't just set it equal to zero, but if it equals zero, then the people above solved it for you. I suggest you write the problem correctly next time so that you don't get too many unnecessary comments.
