You can put this solution on YOUR website!
y=-2-x
x-y=6
x-(-2-x)=6
x+2+x=6
2x=4
x=2
------------
2-y=6
-y=4
y=-4
-----------
-4=-2-2
-4=-4

Solve the system by the substitution method.
x-y=6
y=-2-x
--------
Substitute for "y" and solve for "x"::
x - (-2-x) = 6
x +2 + x = 6
2x = 4
x = 2
--------------
Solve for "y":
y = -2-x
y = -2-2
y = -4
