Hi, I'm looking for a command to find x from my function (it's a bit long function but i'm writing an example): y=ax+b (for example), and i wanna transform it to expression: x=... by command (I mean determination x from this equation). It's all symbolics. Please, help me!

Use the solve function. Note that since your function is longer than your example (and we do not know what it is), it may not have an analytic solution in x.

Everything would be OK, but when i use this function for y=ax+b i get -b/a. And i don't wanna lose y. I'm trying to find the command to transform y=ax+b to x=y-b/a.
