Step-by-step explanation:
The number can be written as 10(x+2)+y. If y is the digit in units place, then the digit in ten's place will be the digit in the units place of (x+2). That is, if (x+2) has only a single digit, the answer is (x+2), but if (x+2) has more than one digit, consider only the units place of (x+2).
