Use PEMDAS (parentheses, exponents, multiplying & dividing, adding & subtracting)

Let's start with the parentheses.
$(12-9) = 3$
This gives us:
$4 + 3(3)$

We dont have any exponents, so we skip this fase.

Next step is multiplying and dividing.
$4 + 3 * 3 = 4 + 9$

Then, add and subtract from left to right.
$4 + 9 = 13$

So the answer is 13.
