Explanation:

To determine if a number is divisible by 9, the sum of its digits must be divisible by 9. Let's analyze:

- The number is represented as x58y.

- The sum of its digits is \(x + 5 + 8 + y\).

- Simplifying, it's \(x + y + 13\).

- We need \(x + y + 13\) to be divisible by 9.

Let's find the smallest possible value of \(x + y\):

1. If \(x + y = 5\), then \(x + y + 13 = 18\) which is divisible by 9.

2. Any smaller value, such as 4 or 3, results in sums that are not divisible by 9.

Therefore, the least value of \(x + y\) that satisfies this condition is 5.

- Correct Answer: Option 2: 5
