Fill in the blanks:
`64967+________=86109`

Answer

To solve the equation \( 64967 + \_\_\_\_\_ = 86109 \), we need to find the missing number. Let's denote the missing number as \( x \).

### Step-by-Step Solution:

1. **Write the equation**:
\[ 64967 + x = 86109 \]

2. **Isolate \( x \)**:
To find \( x \), we need to subtract \( 64967 \) from \( 86109 \):
\[ x = 86109 - 64967 \]

3. **Perform the subtraction**:
Let's subtract \( 64967 \) from \( 86109 \) step by step:
- Start from the rightmost digit:
- \( 9 - 7 = 2 \)
- \( 0 - 6 \) (we need to borrow, so it becomes \( 10 - 6 = 4 \))
- \( 1 - 4 \) (again, we need to borrow, so it becomes \( 11 - 4 = 7 \))
- \( 6 - 9 \) (we need to borrow, so it becomes \( 16 - 9 = 7 \))
- \( 8 - 6 = 2 \)

Putting it all together, we get:
\[ 86109 - 64967 = 22142 \]

4. **Conclusion**:
Therefore, the missing number \( x \) is:
\[ x = 22142 \]

### Final Answer:
\[ 64967 + 22142 = 86109 \]
