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.
