You can put this solution on YOUR website!
x – 2y = 8
x + y = –1
Since the answer must satisfy both equations, the answer must be
the interception point of two graphs.
see graph below

graph%28200%2C200%2C+-5%2C+5%2C+-5%2C+5%2C+0.5%2Ax-4%2C+-1-x%29
from the graph we can see interception point is (2, -3)
so the answer is x = 2, y = -3
