solving difficult equation

I am stuck trying to solve for B this equation:

\[\exp\left(\frac{B}{\sum_{i=1}^{n}x_{i}}\right)= \sum_{i=1}^{n}z_{i}\exp(Bz_{i})\]

I can't think of a way to approach it to get an exact answer. You might be able to use Lambert's W function to write an equation but you are going to have to approximate the answer.

Thanks, I have used the link you shared. However, it is still not clear to me how I am supposed to approximate?
