    Word Problem work

    Two Workers do a job in 12 hours working together

    One worker does half then other one does other half they finish in 25 days

    how long will it take each alone?

    (1/12)x+(1/12)y=1

    I think you means 12 days not hours.

    Let x be the time it takes the first worker. Let y be the time it takes the second worker. When working together we have \frac{12}{x}+\frac{12}{y} = 1. When the first worker does half the full job in x days so it takes him x/2 days to do half-the job. Likewise it does the other worker y/2 days. So x/2+y/2 = 25. Now solve these equations.
