Lets solve this with elimination.
Add both equations together, you will notice the y terms cancel each other out because "y-y = 0". This is what we want.

The result is:
\(3x = -12\)
Divide both sides by 3
\(x = -4\)

To find y-value, plug in x=-4 into 1st equation:
\(2(-4) +y = -8\)
-8 +y = -8
y = 0

Solution is  (-4,0)
