Use The Relationship
to convert this log equation to the corresponding exponential form. . . . . .
Then solve the resulting quadratic by taking square roots.

Subtract the ln(2x) over to the left-hand side, apply a log rule
to combine the two logs into one, and then convert the resulting log equation to the corresponding exponential equation. . . . . .
Then solve the resulting rational equation.

Since this is already in the form "log(something) equals log(something else)", just set the arguments equal. Then solve the resulting cubic equation.
