See a solution process below:

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 #color(red)(9387)# to each side of the equation to solve for #n# while keeping the equation balanced:

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

#n - 0 = 12834#

#n = 12,834#
