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. |
