Simplifying Equations



Hi,
I do not know if there is a general wy to simplify equations in the
desired form. What I usually do is to mix Maxima abilities with my
own. So to discover what would you simplify you can apply helper
functions, life factor, ratsimp and expand

In you example

eq: a*x + b*x  = c*x;
eq1: factor(eq);
eq2:eq1/x;

In eq1 you realize that x can be eliminated and you do it in eq2

Another why of proceeding is to move everything to the same side of
the equation and try to apply more sophisticated functions

eqnew :  lhs(eq) - rhs(eq)

and then work out eqnew.

I hope it helps, maybe somebody else can give a less newbie solution.
