If x and y are integers and x>0, is y>0?
1. 7x - 2y > 0
2. -y< x
OA is E.
I totally understand statement 1, but how do you solve for statement 2.
HELP!!!! Don't Understand Statement 2!

Statement (2)
-y<x
y > -x
if x= 4
y > -4
y could be -2 or 4, since we have both the cases i.e. positive and negative. Insufficient.
Combining (1) & (2)
7x > 2y
7x/2 > y
y>-x
we get a range
-x < y < 7x/2
y can be negative as well as positive. Insufficient.
Thus, E is the answer.
-y<x
y > -x
if x= 4
y > -4
y could be -2 or 4, since we have both the cases i.e. positive and negative. Insufficient.
