Well the first two equations give you that b - a = ab, which means that b = ab + a, with a = b/(b+1). You should post the original question. If you do, then we might be able to provide a more specific answer.

Sorry, do not have the complete question. I remember these equations from a class that I took.
And I made a typo in the first equation. It should be a+b=c.
But, your deduction sure helps, Danaj. Thanks.
