0=-4x-4
Consider the first equation. Insert the known values of variables into the equation.
-4x-4=0
Swap sides so that all variable terms are on the left hand side.
-4x=4
Add 4 to both sides. Anything plus zero gives itself.
x=\frac{4}{-4}
Divide both sides by -4.
x=-1
Divide 4 by -4 to get -1.
y=0 x=-1
The system is now solved.
