55090÷а+=9654

To solve the equation \( \frac{55090}{a} + 9654 = 0 \), we first isolate the term involving \( a \).

1. Subtract \( 9654 \) from both sides: \[ \frac{55090}{a} = -9654 \]

2. Multiply both sides by \( a \) to get rid of the fraction: \[ 55090 = -9654a \]

3. Divide both sides by \( -9654 \): \[ a = \frac{55090}{-9654} \]

4. Now, calculate the value of \( a \): \[ a \approx -5.71 \]

Thus, the value of \( a \) is approximately \( -5.71 \).
