# How do you solve 9x = 27?

$9 x = 27$
Divide both sides by $\textcolor{red}{9}$.
$\implies \frac{9 x}{\textcolor{red}{9}} = \frac{27}{\textcolor{red}{9}}$
$\implies \frac{9 x}{\textcolor{red}{9}} = \frac{9 \cdot 3}{\textcolor{red}{9}}$
$\implies \frac{\cancel{9} x}{\cancel{\textcolor{red}{9}}} = \frac{\cancel{9} \cdot 3}{\cancel{\textcolor{red}{9}}}$
$\implies x = 3$
