Solve system of equations in Wolfram|Alpha?

Hi, I tried to solve the following set of equiations but Mathematica seems not to be able to solve it, asking me to check spelling, etc. solve (O-x)(N-x-y-z)=(A-x-y)(B-x-z) , (P-y)(N-x-y-z)=(A-x-y)(C-y-z), (Q-z)(N-x-y-z)=(B-x-z)*(C-y-z) for x ,y, z

Wow, impressive Bill, it worked!!!

You took a lot of time to redact the step by step procedure, I really appreciate it, I owe you one!

BIG THANKS!!!

Javier, please always include the source code in order to be able to understand what the issue is.

I tried with this and it seems to work:

Solve[
 {(o - x) (n - x - y - z) == (a - x - y) (b - x - z),
  (p - y) (n - x - y - z) == (a - x - y) (c - y - z),
  (q - z) (n - x - y - z) == (b - x - z) (c - y - z)},
 {x, y, z}]

Thanks Gustavo!!!!

I am totally new here at wolfram, so I am no familiar with the notation, syntax, etc.

What I tried was the expresion: solve (O-x)(N-x-y-z)=(A-x-y)(B-x-z) , (P-y)(N-x-y-z)=(A-x-y)(C-y-z), (Q-z)(N-x-y-z)=(B-x-z)*(C-y-z) for x ,y, z

Which, for what I read, is similar to yours changing the notation.

Nevertheless I tried yours, copy and paste, and still have no answer... enter image description here
