$-5 \times |-8-5p|=-73+8$
Calculate the sum$-5 \times |-8-5p|=-65$
Divide both sides of the equation by $-5$$|-8-5p|=13$
Use the absolute value definition to rewrite the absolute value equation as two separate equations$\begin{array} { l }-8-5p=13,\\-8-5p=-13\end{array}$
Solve the equation for $p$$\begin{array} { l }p=-\frac{ 21 }{ 5 },\\-8-5p=-13\end{array}$
Solve the equation for $p$$\begin{array} { l }p=-\frac{ 21 }{ 5 },\\p=1\end{array}$
The equation has $2$ solutions$\begin{align*}&\begin{array} { l }p_1=-\frac{ 21 }{ 5 },& p_2=1\end{array} \\&\begin{array} { l }p_1=-4.2,& p_2=1\end{array}\end{align*}$
