This is better explained with simple example. Suppose I have these 2 equations
eqs:=[3*a+4*b = 3*x, 5*a+7*b = 7*x];
What I want is to solve for (a/x) and (b/x) from the above, and not for "a" and "b".
Currently, I do this manually as follows. First divide both equations by 'x' to obtain the ratio. I had to do this manually as writing eqs/x gave expression which was hard to work with for what I want to do. I could not simplify it for what I wanted. So I typed this
eqs2:=[3*(a/x)+4*(b/x)=3,5*(a/x)+7*(b/x)=7]; %manually typed !
Now used algsubs to replace (a/x) by new variable z1, and replace (b/x) by new variable z2, then solve for z1,z2 (btw, I had to do algsubs one at a time. (need to look at this later, but not impotant)
Is there a way or function(s) to automate this. The hard part is telling Maple to use the ratio as new variable starting from set of equations.
