?

x = 6

Step-by-step explanation:

Sophia wrote the number 41.

Step-by-step explanation:

Let x by the two-digit number written by Sophie. Max appended a 3, so the new number is 10x+3.

The difference between Max's and Sophie's numbers is 372:

(10x+3)-x=372

9x+3=372

9x=369

x=41.

So, Sophie's number was 41.
