# How do you solve for c in 3abc + b = 5?

Feb 17, 2016

$c = \frac{5 - b}{3 a b}$

#### Explanation:

Given
$\textcolor{w h i t e}{\text{XXX}} 3 a b c + b = 5$

Subtract $b$ from both sides:
$\textcolor{w h i t e}{\text{XXX}} 3 a b c = 5 - b$
Divide both sides by $\left(3 a b\right)$
$\textcolor{w h i t e}{\text{XXX}} c = \frac{5 - b}{3 a b}$
