See a solution process below:

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

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

$n - 9387 = 3447$ $n - 9387 = 3447$

Now, we can add $9387$ $color(red)(9387)$ to each side of the equation to solve for $n$ $n$ while keeping the equation balanced:

$n - 9387 + 9387 = 3447 + 9387$ $n - 9387 + color(red)(9387) = 3447 + color(red)(9387)$

$n - 0 = 12834$ $n - 0 = 12834$

$n = 12, 834$ $n = 12,834$
