2,9-x=14,7

To solve the equation \( 2.9 - x = 14.7 \), follow these steps:

1. Start by isolating \( x \). You can do this by subtracting \( 2.9 \) from both sides of the equation: \[ -x = 14.7 - 2.9 \]

2. Calculate \( 14.7 - 2.9 \): \[ 14.7 - 2.9 = 11.8 \]

3. Now, your equation is: \[ -x = 11.8 \]

4. Multiply both sides by \(-1\) to solve for \( x \): \[ x = -11.8 \]

So, the solution is \( x = -11.8 \).
