I need step by step explanation for this!
damaskus [11]

Answer:

61

Step-by-step explanation:

  1. 13 - 1 = 12
  2. 12 ÷ 2 = 6
  3. Put 6 and 1 together: 61

Therefore, the number is 61

Let's check:

  1. 6 × 2 = 12
  2. 12 + 1 = 13

The sum of the two digits is 13, and we got that, so we are correct. The number is 61.
