Answer:

x=12 ; y=8

Step-by-step explanation:

8x+13=11x-23(2 opposite side of a parallelogram is equal)

move the x terms to the left side.

8x-11x=-23-13

-3x=-36

3x=36

x=12

2y+12=4y-4(2 opposite side of a parallelogram is equal)

move the y terms to the left side

2y-4y=-4-12

-2y=-16

2y=16

y=8
