Question

In the parallelogram below y=?

Answer 1

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

`5y - 20 = 2y + 25`

Subtract sides 2y

`- 2y + 5y - 20 = - 2y + 2y + 25 \\`

`3y - 20 = 25`

Add sides 20

`3y - 20 + 20 = 25 + 20`

`3y = 45`

Divided sides by 3

`(3)/(3) y = (45)/(3) \\`

`y = 15`

Done....

Answer 2

15

Explanation:

5y - 20 = 2y + 25 (opposite sides of a parallelogram are equal)

5y - 2y = 25 + 20

3y = 45

y = 45/3

y = 15
