I don't know what you mean by "isolate". Maybe the the collect and coeff methods are what you are looking for.
I mean something like
isolate("x + y = 1", x) -> "x = 1 - y" isolate("(y+2)^2+x * (y+2)+1=0", yplus2) -> "y+2 = (-x + sqrt(x^2-4))/2"
For the linear case, check out lsolve. -richy. -- Richard B. Kreckel
