# How do you solve 3(c+5)=12 using the distributive property?

Jun 23, 2017

$c = - 1$

#### Explanation:

What ever is outside the bracket, you multiply it with the terms inside the bracket.
You have to multiply $c$ with $3$ and $5$ with $3$.

$\therefore 3 c + 15 = 12$

$3 c = - 3$

$c = - 1$

$c = - 1$

#### Explanation:

First, you distribute $3$ to $c$ and to $5$.
That would be $3 \left(c\right) + 3 \left(5\right) = 12$.

So, $3 c + 15 = 12$.

$3 c = - 3$
$c = - 1$

Using distributive property, it is,
$= 3 \cdot c + 3 \cdot 5 = 12$
$= 3 c + 15 = 12$
$= 3 c = 12 - 15$
$= 3 c = - 3$
$= c = \frac{- 3}{3}$
$\textcolor{red}{= c = - 1}$
