To solve the equation \( \frac{n}{5} + 10 = -20 \), follow these steps:
-
Subtract 10 from both sides: \[ \frac{n}{5} = -20 - 10 \] \[ \frac{n}{5} = -30 \]
-
Multiply both sides by 5 to isolate \( n \): \[ n = -30 \times 5 \] \[ n = -150 \]
So, the solution is \( n = -150 \).
The correct response is: -150.
