How do you solve 3(4x+5)=12?

May 31, 2017

$x$$=$$\frac{7}{12}$

Explanation:

Steps:

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

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

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

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

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

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

$12 x$$=$$7$

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

You cannot simplify it, so $\frac{7}{12}$ is your final answer!

I hope this helps!
All the best,
