I know we can solve e^x=x by the Lambert W function, but is it possible to solve the following equation:
a*(e^(2x)e^x)+b*x=c in terms of a, b, and c.

Welcome to PF;
And you want to find x given m and k. That help?

Thank you Simon. Yes. I am wondering if there is some special function can solve this problem, i.e. given the values of a,b,c (or m,k in your equation) I can find out the value of x without looking at the graph.
