    Solves a transcendental equation with respect to the given
    symbol. Various equations containing mixed linear terms, powers,
    and logarithms, can be solved.

    Only a single solution is returned. This solution is generally
    not unique. In some cases, a complex solution may be returned
    even though a real solution exists.
