Please help me out :)

Answer:
Step-by-step explanation:
In a Parallelogram the sides opposite to each other are equal.
So,
5y - 20 = 2y + 25
⇒5y - 2y = 25 + 20
⇒ 3y = 45
⇒ y = [tex]\frac{45}{3}[/tex]
⇒ y = 15
Answer:
y = 15.
Step-by-step explanation:
Opposite sides are equal so we have the equations:
3x + 7 = 5x - 17
5y - 20 = 2y + 25
From the second equation:
3y = 45
y = 15 answer.
