7х +11,9 =0;

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

1. Isolate the term with \(x\): \[ 7x = -11.9 \]

2. Divide both sides by 7: \[ x = \frac{-11.9}{7} \]

3. Calculate the value: \[ x \approx -1. Seven \]

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