Question

Which quadrant does the solution of the system fail?

x+y=4
2x-y=2

Please help I don't know what to do. I don't what the answer, just want to be guided to it! Thank you (:

Answer 1

2 x + 2 y = 8
2 x - 1 y = 2
------------- subtract
0 x + 3 y = 6
y = 2
so
x = 2
x and y are both positive, first quadrant, upper right
