# How do you solve 4<c/5?

Feb 1, 2017

See the entire solution process below:

#### Explanation:

Multiply each side of the inequality by $\textcolor{red}{5}$ to solve for $c$ while keeping the inequality balanced:

$\textcolor{red}{5} \times 4 < \textcolor{red}{5} \times \frac{c}{5}$

$20 < \cancel{\textcolor{red}{5}} \times \frac{c}{\textcolor{red}{\cancel{\textcolor{b l a c k}{5}}}}$

$20 < c$

To solve in terms of $c$ we must reverse or "flip" the inequality:

$c > 20$
