# How do you solve  7a - 3 = 3 - 2a ?

Oct 5, 2016

$\textcolor{g r e e n}{a = \frac{2}{3}}$

#### Explanation:

Given
$\textcolor{w h i t e}{\text{XXX}} 7 a - 3 = 3 - 2 a$

Add $2 a$ to both sides:
$\textcolor{w h i t e}{\text{XXX}} 9 a - 3 = 3$

$\textcolor{w h i t e}{\text{XXX}} 9 a = 6$
Divide both sides by $9$
$\textcolor{w h i t e}{\text{XXX}} a = \frac{2}{3}$
