Answer:
y = 1
x = -0.75
Step-by-step explanation:
The alternate angles theorem states that if two parallel lines are cut by a transversal, then each pair of alternate interior angles are equal.
21y - 1 = 4x + 23
21y - 24 = 4x
5.25y - 6 = x
21y - 1 = 4x + 23
21y = 4x + 24
y = 4/21(5.25 - 6) + 1.14
y = 1 - 1.14 + 1.14
y = 1
5.25(1) - 6 = x
-0.75 = x
