I think you made an error here.
The question states that 3 people worked but what about Bill's wife?
Bill + his wife + Christine + Max = 4 people
I will assume that you did not mistype anything.
Let M = the hours that Max worked.
==================================
Bill = 2(M + 5) + 3 hours
Christine = M + 5 hours
Max = M hours
All three worked 62 hours.
2(M + 5) + 3 + M + 5 + M = 62 hours
2M + 10 + 3 + 2M + 5 = 62 hours
4M + 18 = 62 hours
4M = 62 - 18 hours
4M = 44 hours
M = 44/4 hours
M = 11 hours
So, Max worked 11 hours assuming that Bill's wife did not work.

The other answer to this is absolutely correct, it's just that I had to respond because the person who answered it somehow managed to not understand English sentence structure and assumed "his wife, Christine" implied 2 people, when it in fact gives his wife the name Christine. But I'll put the process of solving here anyway.
If Max's hours worked = n, then
Christine's hours worked = n+5 and Bill's hours worked = 3+2(n+5)
so
%282%28n%2B5%29%2B3%29%2B%28n%2B5%29%2Bn=62
%282n%2B10%2B3%29%2B2n%2B5=62
4n%2B18=62 so 4n=62-18
4n=44 so n=44%2F4
n=11
