A number consists of two digits whose sum is 5. If 9 is added to the number, its digits are interchanged. Which of the given steps is/are CORRECT to find the number?

Step 1: Let the units digit be x.
Step 2: Then, tens digit = (5 - x)
Number =
= 50 - 10x + x
= 50 - 9x
Step 3: Adding 9 to the number (50 - 9x), we get 59 – 9x
Step 4: Number with digits interchanged = 10x + (5 - x) = 9x + 5
Step 5: 59 - 9x = 9x + 5
Step 6: Therefore, units digit = 3 and tens digit = 2
Step 7: Hence, number = 23
