Dear users of R,
I'm trying to solve the following 2 equations simultaneously in R for "x" and "y". I couldn't get through due to my limited knowledge of R.

3=1-[(x-1)!(2x-y-1)!/(2x-1)!(x-y-1)!] 

6={[(x-y-1)!/(x-1)!]-[3(2x-y-1)!/(2x-1)!]+[2(3x-y-1)!/(3x-1)!]}/{[(x-y-1)!/(x-1)!]-[(2x-y-1)!/(2x-1)!]}

obviously, ! is factorial.
kindly help me out on it or at least suggest something.
I'll be extremely grateful.
Eliza
