Very much first, most important - Write down definitions!

Y = Terry's Hours / Job
M = Tom's Hours / Job

1/Y = Terry's Job / Hour
1/M = Tome Job / Hour

Worked together for 2 hours

(2 hr)(1/Y + 1/M) + (1 hr)(1/Y) = 1 Job

anonymous · Answer

Terry's hour is y  and Tom's hour is x
 ->        y = x + 2   ( hr)
The portion both work for 2 hours:
=   2/x  + 2/(x +2) 
= ....
The remained portion:
= 1 - ...
