5,6,7 is the answer to your question. Hope this helps!!
It is 9 and 1/4. This is because 9 goes into 37 nine times with a remainder where is where the 1 in 1/4 comes from.
Let's say 2y < 18 - 2x
so
4x - 2y > 3
4x - 18 - 2x > 3
2x > 21
2x/2 > 21/2
x > 10.5
2y < 18 - 2(10.5)
2y < 18 - 21
2y < -3
y < 1.5
