Answer:

x=12

Explanation:

In a parallelogram opposite sides are equal

Therefore:


3x + 7 = 5x - 17

and


5y - 20 = 2y + 25

To find x move all the terms from the right side to the left side or vice versa. I'll use the left this time (Remember that when you transfer, the positive number becomes the negative and the negative number becomes positive)


5x - 3x - 17 - 7 = 0


2x - 24 = 0

Transfer 24 to the other side


2x = 24

Divide both by 24


(2x = 24)/(2)


x = 12
