$- \frac{1}{3x} + 5 = - \frac{6}{x} \\ 5 = - \frac{6}{x} + \frac{1}{3x} = - \frac{18}{3x} + \frac{1}{3x} = - \frac{17}{3x} \\ 3x = - \frac{17}{5} \\ \boldsymbol{x =} - \frac{17}{5} \div 3 = - \frac{17}{5} \div \frac{3}{1} = - \frac{17}{5} \times \frac{1}{3} = - \frac{17}{15} \boldsymbol{= - 1 \frac{2}{15}}$
