It could be many things. If x and y are different non-zero positive integers, then x=1 and y=4. (if x is zero, Y is 6 ; if y is zero, x is 3)
Otherwise, any answer would be correct where x = (6-y)/2 or y=6-2x.
For two unknowns, x and y, you need two independent equations to get numerical solutions.

[ y = -2x + any other number ] is parallel to [ y = -2x + 6 ].
x=0 y=6
x = 2y = 4
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
The answer is - not are - (-6, 9).
