To solve the equation \( \frac{n}{7} + 12.2 = -5 \), follow these steps: 1. Subtract 12.2 from both sides of the equation: \[ \frac{n}{7} = -5 - 12.2 \] 2. Calculate the right side: \[ \frac{n}{7} = -17.2 \] 3. Multiply both sides by 7 to isolate \( n \): \[ n = -17.2 \times 7 \] 4. Calculate the multiplication: \[ n = -120.4 \] Thus, the solution is: \[ \boxed{-120.4} \]
