Answer 3

your just gonna have to start subbing to see which one is true.
(1,1)
2x + y > 8
2(1) + 1 > 8
2 + 1 > 8
3 > 8 (incorrect)
no need to try the other equation because they both have to be true
(3,4)
2x + y > 8
2(3) + 4 > 8
6 + 4 > 8
10 > 8 (correct)
now we try the other one
(3,4)
x - y < 2
3 - 4 < 2
-1 < 2 (correct)
Both of these are correct, so HelloGoodmorning is correct...it is (3,4)
