$8 \frac{4}{5} - \frac{2}{3} - x = 3 \frac{1}{10}$

$\frac{44}{5} - \frac{2}{3} - x = \frac{31}{10}$

$\frac{44}{5} - \frac{2}{3} - \frac{31}{10} = x$

$x = \frac{44 \times 6}{5 \times 6} - \frac{2 \times 10}{3 \times 10} - \frac{31 \times 3}{10 \times 3}$

$x = \frac{ 264 }{30} - \frac{20}{30} - \frac{93}{30}$

$x = \frac{151}{30}$

$x = 5 \frac{1}{30}$
