$a = - 6$ $a=-6$

Let's start by distributing the $3$ $3$ to both of the terms in the parenthesis on the left. We get

$6 a - 24 = 8 a - 12$ $6a-24=8a-12$

Let's add $24$ $24$ to both sides to get

$6 a = 8 a + 12$ $6a=8a+12$

Next, let's get our variables on the left side. This can be done by subtracting $8 a$ $8a$ from both sides. We get

$- 2 a = 12$ $-2a=12$

Our last step is dividing both sides by $- 2$ $-2$ , which gives us

$a = - 6$ $a=-6$

Hope this helps!
