#### Explanation:

Divide each side of the equation by $\textcolor{red}{7.9}$ to solve for $r$ while keeping the equation balanced.

$\frac{7.9 r}{\textcolor{red}{7.9}} = - \frac{19.75}{\textcolor{red}{7.9}}$

$\frac{\textcolor{red}{\cancel{\textcolor{b l a c k}{7.9}}} r}{\cancel{\textcolor{red}{7.9}}} = - 2.5$

$r = - 2.5$
