$x$ $=$ $7/12$

Steps:

Step 1: Take out those parentheses by mutiply 3 with the numbers inside the parentheses.

$3$ $($ $4$ $x$ + $5$ ) $=$ $12x+5$

So now, the equation will be, $12x+5$ $=$ $12$

Step 2: Now we are going to leave $x$ by itself on one side.

$12x+5$ $=$ $12$

$12x$ $=$ $12$ $-$ $5$

$12x$ $=$ $7$

Then, after you divide take $12$ to the other side, you will have your answer:
$x$ $=$ $7/12$

You cannot simplify it, so $7/12$ is your final answer!

I hope this helps!
All the best,
