New to Sage and just trying to solve a simple system of equations. The system is below:
I want to find the equilibrium solutions, solving for x, y, z, w, when equations f1-f4 are equal to zero. So I try:
Unfortunately this causes Sage to hang (or it takes a remarkably long time to solve that I interrupt the process). This problem shouldn't be difficult to solve, but I am at a loss as to what to do. Perhaps I am going about this the wrong way??
You should be using Groebner bases (and the Singular interface) instead of general purpose symbolics (via Maxima) for systems of polynomial equations. The standard way of doing what you want is to compute a lexicographic Groebner basis along the lines of what I commented here.

I think your original question was edited, because when I answered before there were the lines
I added multiplication signs between cz and cy and pasted the following code into the cell
I then get the answer
I just see that * sign is removed from normal text postings on this site, so your original system probably contained all *. In the current form with all * I get no solution either. - sorry
PS: Question to the site admins: Is it a bug or a feature of this site that * is removed?
