$a = 6$ $a=6$

First, move all the $a$ $a$ s to one side by subtracting $3 a$ $3a$ on both sides:

$8 a - 3 a = 3 a + 30 - 3 a$ $8a-3a=3a+30-3a$

Simplify:

$5 a = 30$ $5a=30$

Now divide both sides by $5$ $5$ to solve for $a$ $a$ :

$\frac{5 a}{5} = \frac{30}{5}$ $(5a)/5=30/5$

Simplify:

$a = 6$ $a=6$
