algorithm to simlify eqn

an anyone please help me to derive the
algorithm to simplifying linear equation?

For example, I have one eqn like, (3 X1+ 4
X2 +5) /5 + (3 X1-7 X2 - 6)/6 = 2

it should give 23 X1 - 11 X2 -60 =0;

In general it should outputted complex
equations in form of A X1 + B X2 +.... + c =0

actually i am trying to develop an apllication which generates equation in complex mode like my examp but variables are not less than 10 and i need to simplify it to feed it in next module which takes eqn only as A X1 + B X2 +.... + c =0

thanks in advance.

in that example you need distribute / over + and -, then sort out constants for each variable, you'd need a parser though and a reduction engine

thanks,
Got some idea. Can i get those required stuffs/ engine readily available or i have to develop those my own? If possible, if you can give some related codes or available sources/example, it will be a great to me .
Thanks

easiest would be to use one already available like haskell ;) google around for parsers calculators and equation solvers etc.. theres loads of stuff available.

I'm looking for the same thing, but am having no luck finding anything. Most of the things I've found are equation solvers that are better than the eval() function (ie fastmath), but not finding anything that will reduce a string into a simpler equation. Anybody know of some code to do this?

This is sort of not pertinent, but, just to keep things straight... You posted:

Actually, the coefficient of X1 is 33, not 23. Perhaps a slip of the typing fingers?

that's not really relevant.

the equation illustrated his point, regardless of whether it was correct or not :P
