Answer:

  (x, y) = (10, 4)

Step-by-step explanation:

Opposite sides are the same length, so ...

  ON = LM

  6x -3 = 4x +17

  2x = 20 . . . . . . . . add 3-4x

  x = 10

__

  OL = NM

  x -5 = 3y -7

  10 -5 + 7 = 3y . . . . . substitute x, add 7

  12/3 = y = 4 . . . . . .  simplify, divide by 3

The values of x and y are 10 and 4, respectively.
