#### Explanation:

First, we can call the number we are looking for $n$.

Next, we can write this equation from the information provided in the problem.

$n - 9387 = 3447$

Now, we can add $\textcolor{red}{9387}$ to each side of the equation to solve for $n$ while keeping the equation balanced:

$n - 9387 + \textcolor{red}{9387} = 3447 + \textcolor{red}{9387}$

$n - 0 = 12834$

$n = 12 , 834$
