The Attempt at a Solution

Hello Suzana, welcome to PF !

I can follow the problem statement, but I don't see any relevant equations. If you have unknowns, you need equations. You need as many equations as you have unknowns, so you better start gathering some.
Then you start with an attempt at solution and then you can expect some help on PF. That's the way it works here, can't help it . But there's good reasons for rules like that.
