a friend gave me this equation and required that i solve it:

I could only solve it graphically and the answer was (x = 4),

so i wonder if there is an algebraic solution for it ?

In summary, the conversation discusses a difficult equation given by a friend and the difficulty of solving it algebraically. It is suggested to use calculators or Newton's method to solve it, but it is also noted that the solution may be complex and not easily expressed.

I don't think there is any way to solve it algebraically.

With such equations, it's easy to create them, while terribly annoying to solve without calculators to solve it numerically for you. I think your friend may have caused you a headache for laughs

edit: Sorry I just realized that's a dumb idea. Yeah, I don't think there's any way to solve it analytically.

maybe that's the only analytic way to solve it, but i don't know how to use this method

If there isn't such a nice easy to spot idea, then the solution is almost certainly going to be nasty, transcendental and impossible to write down in any nice way, so don't bother to try.
