This is part of an optimization problem, and I'm finding the zeros of the first derivative which is f'(x) = (7-x)/x - ln(x)(adsbygoogle = window.adsbygoogle || []).push({});

Is there any way to solve this for an exact answer? I've tried and there doesn't seem to be a way. Is it even possible to solve for an exact answer?

0=(7-x)/x - ln(x)

Thanks.
