Question

Sarah drove 3 hours more than michael on their trip to texas. if the trip took 37 hours, how long did sarah and michael each drive?

Answer 1

37-3 = 34

34/2 = 17

Michael drove 17 hours

Sarah drove 20 hours  (17+3)

Answer 2

The algebraic expression would be x+x+3=37

The answer would be that Michael drove 17 hours and Sarah drove 20 hours.

Work:

x+x+3=37
(combine like-terms)
2x+3=37
(subract 3 from each side of the equation)
2x=34
(divide 2 from each side of the equation)
x=17

17 would be the number of hours that michael drove but since sarah drove 3 hours longer you add 3 so then sarah drove 20 hours.
