I don't think this equation can be solved analytically, but I may be wrong. Here is how I found the solution.

I used the following command to plot the function


I see that this is zero at two points near -7 and 0. So I typed the following commands to find the root in that region


This gave me -0.06139800265618307 and -7.529020910031573.
