The sum of the digits of a two-digit number is 15 and the difference between the digits is 3. What is the two-digit number?

Answer»

Cannot be determined



Let the ten's DIGIT be X and unit's digit by y

Then, x + y = 15 and x - y = 3 or y - x = 3

Solving x + y = 15 and x - y = 3, we get: x = 9, y = 6

Solving x + y = 15 and y - x = 3, we get: x = 6, y = 9

So, the number is either 96 or 69.

Hence, the number cannot be determined.
