    Reduce the problem. Rename constants and variables, then remove constants while problem remains unsolvable with maxima 5.39.0 (%i31) neqs:eqs,[k1=d,x1=e,j1=f,k2=g,j2=h,mu=m,x2=x,x3=y,u1=z]; (%o31) [d*e*y-f*x = 0,g*x*y-e*h = 0,a*z+(m*(x+e))/y-c*x-b*e = 0] (%i32) subst([a=1,b=1,c=1,d=1,e=1,f=1,m=1],neqs); (%o32) [y-x = 0,g*x*y-h = 0,z+(x+1)/y-x-1 = 0]; (%i33) algsys(%,[x,y,z]); (%o33) [] This is solvable in 5.38.1, with solution (%o18) [[x = sqrt(h/g),y = (h+sqrt(g)*sqrt(h))/(sqrt(g)*sqrt(h)+g), z...
