Question

Please help me out :)

Answer 1

y = 15.

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.

Answer 2

15

Explanation:

In a Parallelogram the sides opposite to each other are equal.

So,

5y - 20 = 2y + 25

⇒5y - 2y = 25 + 20

⇒ 3y = 45

⇒ y =
`(45)/(3)`

⇒ y = 15
