2x − y = -2
3y = 6 − 5x

x = 0, y = 2

x = 2, y = 0

x = 2, y = 2

x = 0, y = -2

If you're asking which is correct, the answer is the first one: x = 0 and y = 2. You figure this out by substituting in the values and seeing that they are correct, so:
(2 × 0) - 2 = -2
0 - 2 = -2
(3 × 2) = 6 - (5 × 0)
6 = 6 - 0
I hope this helps!
