To solve the equation \( 5(n - 6) = 20 \), you can follow these steps:
-
Distribute the 5 on the left side: \[ 5n - 30 = 20 \]
-
Add 30 to both sides to isolate the term with \( n \): \[ 5n - 30 + 30 = 20 + 30 \] \[ 5n = 50 \]
-
Divide both sides by 5 to solve for \( n \): \[ n = \frac{50}{5} \] \[ n = 10 \]
Thus, the value of \( n \) is \( \boxed{10} \).
