8. find the values that make this a parallelogram

 7) x = 29 and y = 28

 8) x = 5 and y = 7

Step-by-step explanation:

7)

Parallelogram

So

4x + 2x + 6 = 180

6x + 6 = 180

6x = 174

 x = 29

and

3y - 20 + 4y + 4 = 180

7y - 16 = 180

7y = 196

y = 28

8)

x - 1 = 2x - 6

-x = -5

x = 5

and

3y - 3 = 2y + 4

 y = 7
