55090÷а+8867=9654

To solve the equation \( 55090 \div a + 8867 = 9654 \), follow these steps:

1. Isolate the term with \( a \): \[ 55090 \div a = 9654 - 8867 \]

2. Calculate \( 9654 - 8867 \): \[ 9654 - 8867 = 787 \] So the equation simplifies to: \[ 55090 \div a = 787 \]

3. Now, multiply both sides by \( a \) to eliminate the division: \[ 55090 = 787a \]

4. Finally, divide both sides by 787 to solve for \( a \): \[ a = \frac{55090}{787} \]

5. Now calculate the value: \[ a \approx 70 \]

Thus, \( a \) is approximately \( 70 \). If you need an exact calculation: \[ a = 70 \]
