0,31x + 1,2 = 1,2124

To solve the equation \( 0.31x + 1.2 = 1.2124 \), follow these steps:

1. Subtract \( 1.2 \) from both sides of the equation:

   \[ 0.31x = 1.2124 - 1.2 \]

   \[ 0.31x = 0.0124 \]

2. Divide both sides by \( 0.31 \) to solve for \( x \):

   \[ x = \frac{0.0124}{0.31} \]

Now let's calculate that:

\[ x \approx 0.04 \]

Thus, the solution to the equation is:

\[ x \approx 0.04 \]
