## Main Question or Discussion Point

I have a set of several equations -

The coefficients are rather large.

I thought I would be smart and not go through all the mess of solving them by hand

I have used wxMaxima some and carefully entered each equation into wxMaxima - using its Solve function

I'm getting:

[[X1=-230942730/(%r1-23900000),

X2=112626/3125,

Tx1=%r1,

Tx2=333975528125/18771]]

what is up with the %r1?

For what it's worth the Tx2 - I feel pretty good about that number it seems about what I would expect, X2 - I could believe that number - not too bad from my gut feel.

anybody here use wxMaxima and know about this?

OR

Can anybody suggest a "free" software package that could solve ~ 7 equations 7 unknows with large numbers?
