Answer

Thus our answer is \(\boxed{(0,-2)}\).

Steps

Step 1 :We can find \(x\) by adding the first equation to the second. From \[x+y+x-y=2-2\] we get \[2x=0\], so \[x=0\].

Step 2 :Substituting into the first equation, we can find \(y\): \[x+y=-2 \implies y=-2-x=-2-0=-2\].

Step 3 :Thus our answer is \(\boxed{(0,-2)}\).
