A) x - 8 = 1
Eliminate
B) 2x - 8 = 1
C) x - 8 = 60
D) 2x - 8 = 60

Please pardon the eliminate underneath A) for that was unintentional

An hour is 60 minutes.
The trip to the arena + The return drive = 60 minutes.
Since the return drive is 8 minutes shorter, if you added 8 minutes it would be the same length as the trip to the arena.
The return drive + 8 minutes = The trip to the arena
Let's represent these two equations with variables.
x + r = 60
r + 8 = x

What we do now is use substitution. Since r + 8 = x, we can replace x from the first equation with r + 8.

x + r = 60
r + 8 + r = 60
2r + 8 = 60
2r = 52
r = 26

Then use r in an earlier equation to find a.

r + 8 = x
26 + 8 = x
so the answer should be D hope this helps you
