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} $ $\displaystyle 2+3x^2=5x$ $\displaystyle 3x^25x+2=0$ $\displaystyle (3x2)(x1)=0$ $\displaystyle x=1$ or $\displaystyle x=\frac{2}{3}$
