Answer
$\color{blue}{x=\dfrac{92}{5}}$
Work Step by Step
Add $12$ to both sides to obtain:
\begin{align*}
5x-12+12&=80+12\\
5x&=92\end{align*}
Divide both sides by $5$ to obtain:
\begin{align*}
\frac{5x}{5}&=\frac{92}{5}\\\\
x&=\frac{92}{5}\end{align*}
Therefore, the solution is $\color{blue}{x=\dfrac{92}{5}}$.
