The difference between the digits of a two-digit number is 3 and the total of the digits is 15. What is the value of the two-digit number?
A. 69 B. 78 C. 96 D. Cannot be determined
Explanation: Let x be the tenth digit and y be the unit digit.x + y = 15 and x - y = 3 or y - x = 3 are the results.We get x = 9, y = 6 by solving x + y = 15 and x - y = 3.We obtain x = 6, y = 9 when we solve x + y = 15 and y - x = 3.As a result, the answer is either 96 or 69.As a result, the exact quantity is unknown.
