Answer:
x = 12
y = -2
Step-by-step explanation:
In a parallelogram, the sides opposite each other are equal.
Hence: PQ = SR and PS = QR
2x + 12 = 4x - 12
Rearrange to make x's on one side and the numbers on the other
4x - 2x = 12 + 12
2x = 24
x = 12
____________
y + 25 = 6y + 35
Rearrange to make y's on one side and the numbers on the other
6y - y = 25 - 35
5y = -10
y = -2
