This is a pretty simple problem if you know how to substitute problems.
The answer to this problem is:
x=-1
y=0
Here's the work:
2x+y-(-x)-y=-2-1
2x+x+y-y=-3
3x=-3
x=-1
Then you substitute x into equation 1:
-(-1)+y=1
y=1-(-(-1))
y=1-1
y=0
I hope you understand my work and explanation, you can email me if you have any more questions! Enjoy! ;)
