How do you solve for x in 3x=a?

See a solution process below:

Explanation:

Divide each side of the equation by $\textcolor{red}{3}$ to solve for $x$ while keeping the equation balanced:

$\frac{3 x}{\textcolor{red}{3}} = \frac{a}{\textcolor{red}{3}}$

$\frac{\textcolor{red}{\cancel{\textcolor{b l a c k}{3}}} x}{\cancel{\textcolor{red}{3}}} = \frac{a}{3}$

$x = \frac{a}{3}$

Or

$x = \frac{1}{3} a$
