With this correction made, ln x - 4 ln 3 = ln(5/x)
ln x - 4 ln 3 = ln 5 - ln x

Add ln x and 4 ln 3 to each side:
2 ln x = ln 5 + 4 ln 3
Divide by 2, and you should get

Raise both sides as a power of e, and the answer should be

With a calculator, I get about 20.12, and this checks by graphing calculator methods of solving equations.
