Homework Help: math

May and Bill took 49 hours to complete their History project. They worked separately on their own project. If May had worked 5 hours less and Bill had worked 6 hours more, May would have put in 2 hours more than Bill. How many hours did May put in for the History project?

m+b = 49
(m-5) = 2 + (b+6)

m + b = 45
m - b = 13

2m = 58
m = 29
so, b=16

If May had worked 5 hours less (24), and Bill had worked 6 hours more (22), she'd have put in 2 more hours than Bill.

gotta watch those typos.

m + b = 49
m - b = 13

2m = 62
m = 31
so, b=18

If May had worked 5 hours less (26), and Bill had worked 6 hours more (24), she'd have put in 2 more hours than Bill.
