e^x+x=5

2. Relevant equations

Lambert W-function?

3. The attempt at a solution

I moved everything around and got: Ln(5-x)=5....

It doesn't really help.

I looked at wolframalpha, and it said I need the Lambert W-function (no clue what that is).

Can this equation be solved Without graphing it, only using algebraic methods?
