Solve this system of equations?

Posted 7 years ago

I have two equations with a common variable and I would like to solve for the common variable, how can I do that. I have tried:

Solve[{Ftt == P/A - (P e)/z1+ MDL/z1,Fcw == (n P)/A - (n P e)/z1 + MDL/z1 + MLL/z1},z1]

without success.

I have tried solving for z1 individually for each formula and then equating the two results and simplifying, but that caused terms to drop out which I don't believe is correct

(A MDL-A e P)/(A Ftt-P)=(A MDL+A MLL-A e n P)/(A Fcw-n P) //Simplify

(A (MDL+MLL-e n P))/(A Fcw-n P)

Please make sure you know the forum rules, it is important how you should properly edit code (note how it is framed and syntax-highlighted - if this does not happen your code can be parsed wrongly by the editor and other users will copy with errors): https://wolfr.am/READ-1ST

Trying Reduce:

Reduce[{
  Ftt == P/A - (P e)/z1 + MDL/z1,
  Fcw == (n P)/A - (n P e)/z1 + MDL/z1 + MLL/z1}, z1]
