Answer:
According the the Property of Equality (POE), if a=b and b=c, then a=c.
If -8y + 8 = x and x = -2y + 2, substitute so that it becomes -8y + 8 = -2y + 2.
Solve from there:
Move the y variables to their own side.
-8y + 2y = 2-8
-6y = -6
y = -6
Then plug the y into either equation to find x.
x = -2y + 2
x = -2(-6) + 2
x = 12 + 2
x = 14
Answer:
a=70 vertically opp angles
b=80 linear pair
c=100 corresponding angles
d= 80 linear pair with c
e= 180 -a-d
=180-70-80
=30
