1. Let one number be x.

2. The other number is more than twice the first number. So, it becomes 2x + 1 .

3. The sum of the numbers is:

x + 2x + 1 = 91

4. Simplify to find x :

3x + 1 = 91

5. Solve for x :

3x = 90

x = 30

6. Find the second number:

2x + 1 = 61

7. Check the sum:

30 + 61 = 91

So the two numbers are 30 and 61.
