Answer:
x = 3, y = 2.
Step-by-step explanation:
I assume that O is the point of intersection of the diagonals. The diagonals of a parallelogram bisect each other so here we have AO = OC and DO = OB.
Therefore 5y + 1 = 6y - 1
1 + 1 = 5y - 5y
2 = y.
2(x + 1) = 3x - 1
2x + 2 = 3x - 1
2 + 1 = 3x - 2x
3 = x.
