Multiply through by $6x$. You should get a quadratic equation.

$\displaystyle \frac{1}{3x}+\frac{x}{2}=\frac{5}{6}$

$\displaystyle \frac{1}{3x}(6x)+\frac{x}{2}(6x)=\frac{5}{6}(6x)$

$\displaystyle \frac{6x}{3x}+\frac{6x^2}{2}=\frac{30x}{6} $

$\displaystyle 2+3x^2=5x$

$\displaystyle 3x^2-5x+2=0$

$\displaystyle (3x-2)(x-1)=0$

$\displaystyle x=1$ or $\displaystyle x=\frac{2}{3}$
Thanks from Ole Daniel
