7х +11,9 =0;

To solve the equation \(7x + 11.9 = 0\), follow these steps:

1. Subtract 11.9 from both sides: \[ 7x = -11.9 \]

2. Now, divide both sides by 7 to isolate \(x\): \[ x = \frac{-11.9}{7} \]

3. Calculate the value: \[ x \approx -1.7 \]

Thus, the solution to the equation \(7x + 11.9 = 0\) is: \[ x \approx -1.7 \]
