4,1•(-2)+b=6

To solve the equation \( 4.1 \cdot (-2) + b = 6 \), follow these steps:

1. Calculate \( 4.1 \cdot (-2) \): \[ 4.1 \cdot (-2) = -8.2 \]

2. Now substitute this value back into the equation: \[ -8.2 + b = 6 \]

3. To isolate \( b \), add \( 8.2 \) to both sides of the equation: \[ b = 6 + 8.2 \]

4. Calculate \( 6 + 8.2 \): \[ b = 14.2 \]

Thus, the value of \( b \) is \( 14.2 \).
