Answer:

x = 10; y = 20

Step-by-step explanation:

8x + y = 100     (alternate exterior angles are congruent)

4x + y = 60       (corresponding angles are congruent)

Subtract the second equation from the first equation.

4x = 40

x = 10

Substitute x = 10 in first equation and solve for y.

8(10) + y = 100

y = 20
