Solution 1

The problem states that the sum of two digits of a number is 15 and if 9 is added to the number, the digits are reversed.

Let's denote the tens digit as 'a' and the units digit as 'b'. So, the number is 10a + b.

From the problem, we know that:

  1. a + b = 15
  2. 10a + b + 9 = 10b + a
