Clear[x]; x[y_] = x /. Solve[y == x/a + b, x][[1]] -a (b-y) x[2] -a (b-2) Bob Hanlon ---- Simula <simula at mit.edu> wrote: ============= Hello, I have a very simple question but I didn't find an answer in mathematica help. I use Solve[expression(x,y),x]. Then, x is obtained as a one-to-one function of y. I want to define the function x(y) using the output of Solve. How should I do? Thank you very much for your help.
