May 20, 2017

See a solution process below:

#### Explanation:

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

$\frac{3 x}{\textcolor{red}{3}} \ge \frac{15}{\textcolor{red}{3}}$

$\frac{\textcolor{red}{\cancel{\textcolor{b l a c k}{3}}} x}{\cancel{\textcolor{red}{3}}} \ge 5$

$x \ge 5$
