    so I've got this equation down to

    x*ln(2/x) = 5

    Can someone show/point me to a page where I can see how to solve this. I am under the impression it requires some type of ratio computation.

    (hint: Try graphing the expression on the left.)

    There are no real solutions to that equation. Are you interested in how to find the complex solutions?
