ABCD is a parallelogram. BM= 22-3x, DM=10+9x, AM=7y+13 and CM=2y+38. solve for x and y

Where is M?
I can only assume M is the intersection of the diagonals, since there seems to be a line from each vertex to M.

In a parallelogram, the diagonals bisect each other. That means, assuming that ABCD are the vertices labeled in order,

AM=CM and BM=DM

7y+13 = 2y+38
5y = 25
y=5

22-3x = 10+9x
12x = 12
x=1

Looking at all my assumptions, maybe you can see why it is important to explain fully any diagrams you intend to use...
