Answer:
The answer will turn out to be y= 5 or y= -5.
The start time is 9:15 A.M. I believe.
I took away 6 hours from the elapsed time to get 12:00 P.M. (noon). Then, I took away another 3 hours to get 9:00 A.M. Now, we only have 3/4 hour left. 3/4 of 60 is 45. 60 - 45 = 15. Add 15 minutes to 9:00.
Hope it helps,
