To solve the equation \( 7(n + 4) = 21 \), follow these steps: 1. **Divide both sides by 7** to simplify the equation: \[ n + 4 = \frac{21}{7} \] This simplifies to: \[ n + 4 = 3 \] 2. **Subtract 4 from both sides** to isolate \( n \): \[ n = 3 - 4 \] This gives: \[ n = -1 \] Thus, the solution is \( n = -1 \).

7(n + 4) = 21

1 answer

To solve the equation \( 7(n + 4) = 21 \), follow these steps:

Divide both sides by 7 to simplify the equation:

\[ n + 4 = \frac{21}{7} \]

This simplifies to:

\[ n + 4 = 3 \]
Subtract 4 from both sides to isolate \( n \):

\[ n = 3 - 4 \]

This gives:

\[ n = -1 \]

Thus, the solution is \( n = -1 \).
