A)
Kim's age=k
Sister's age=s
k=2s
k+s=36
b)
k=2s
k+s=36
k=36-s
2s=36-s
3s=36
s=12
12*2=24
Kim is 24 and her sister is 12
Hope this helps :)
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
