Explicación paso a paso:

$5\left(-16\div \left(21-31\right)-3\left(-7+15\right)\:\right)=\\\\\\-16\div \left(21-31\right)-3\left(-7+15\right)\\\\=-16\div \left(-10\right)-3\left(-7+15\right)\\\\=-16\div \left(-10\right)-3\cdot \:8\\\\=\frac{-16}{\left(-10\right)}-3\cdot \:8\\\\\\=\frac{-16}{\left(-10\right)}-24\\\\=-\frac{112}{5}\\\\=5\left(-\frac{112}{5}\right)\\\\=-\frac{5}{1}\cdot \frac{112}{5}\\\\-\frac{112}{1}\\\\=-112$
