Can't figure out this problem
Sorry that I wasn't more specific in the title, but I don't really know what to call this problem...
"In a two-digit number, the ten's digit is 3 more than the one's digit. If the digits are reversed, the difference between the two numbers is 27. Find the two-digit number."
I'm really confused, because unless there's something I'm missing here, 52, 63, and 85 would all work. Problem is, this isn't supposed to be a question with more than one answer, so I'm very lost.
I'd appreciate it if someone could help me figure this out.
