Hello!
I have a little problem here and wonder if anyone know how to solve
this one (programming TI-83). In chemistry we are calculating formulas
for chemical balance.  I solved rhe problem as far as finding
(programming) the value 'K' and 'Q'. for 1 to 3 substances.

       A^a  *  B^b
K= -----------------
      C^c   *  D^d

The problem is to calculate moles for balance (x is onknown) this is
the formula..


      (A-x)^a  *  (B-x)^b
K=-------------------------
     (C+x)^c  *  (D+x)^d           the nominator and numerator sign
should also be reversed (dividing and

creating of substances). I've tried the 'solved- function', but i can
not make it work....!!
