Oops, sorry. The increase is 54 and not 5y. Typo. So the real word problem is
"A two-digit number is increased by 54 when the digits are reversed. If the sum of the digits is 12, find the number."
A two-digit number is increased by 5y when the digits are reversed. If the sum of the digits is 12, find the number.
