Answer:
<em>x = 10; y = 20</em>
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
the answer is 25 squared
x = -10
