Answer:

x = 10

y = 15

Step-by-step explanation:

Angles 8x - 10 and 7x are congruent because they are alternate interior angles of parallel lines cut by a transversal.

8x - 10 = 7x

x = 10

7x = 7(10) = 70

6y + 20 and 7x are supplementary since they are a linear pair.

6y + 20 + 7x = 180

6y + 20 + 70 = 180

6y = 90

y = 15
