Complete the examples, choose the necessary digits from [] and fill in the blanks.

1.

\[ 3 + 3 = 6 \]

The possible pairs are:

• (3, 3)
• (2, 4)
• (4, 2)
• (5, 1)
• (1, 5)

2.

\[ 5 - 3 = 2 \]

The possible pairs are:

• (5, 3)
• (7, 5)
• (4, 2)
• (3, 1)

3.

\[ 10 + 2 = 12 \]

The possible pairs are:

• (10, 2)
• (9, 3)
• (8, 4)
• (7, 5)
• (6, 6)

4.

\[ 6 + 2 = 8 \]

The possible pairs are:

• (6, 2)
• (8, 0)
• (5, -1) - Not possible as per the given digits.
• (7, 1)
• (1, -5) - Not possible as per the given digits.

5.

\[ 11 - 3 = 8 \]

The possible pairs are:

• (11, 3) - 11 is not a single digit. So this option is invalid. Let's assume the intention was to use single digits from the list [1, 2, 3, 4, 5, 6, 7, 8, 9].
• If the first number is 6: [6] - 3 + [x] = 8 => 3 + x = 8 => x = 5. So (6, 5)
• If the first number is 3: [3] - 3 + [x] = 8 => 0 + x = 8 => x = 8. So (3, 8)
• If the first number is 7: [7] - 3 + [x] = 8 => 4 + x = 8 => x = 4. So (7, 4)

Based on the provided digits [1, 2, 3, 4, 5, 6, 7, 8, 9] and the structure of the question:

Corrected answers for 5:

• (6, 5)
• (3, 8)
• (7, 4)
