Resuelve la ecuación: \[ 20(n+8)=4(40+5n) \]

Expandir ambos lados de la ecuación.

\[ 20(n + 8) = 20n + 160 \] \[ 4(40 + 5n) = 160 + 20n \]

Igualar las expresiones expandidas.

\[ 20n + 160 = 160 + 20n \]

Simplificar la ecuación.

Restar \(20n\) de ambos lados: \[ 20n + 160 - 20n = 160 + 20n - 20n \] \[ 160 = 160 \]

La ecuación es una identidad, lo que significa que es verdadera para todos los valores de \(n\). Por lo tanto, la solución es todos los números reales.

\[ \boxed{\text{B. La solución es todos los números reales.}} \]

\[ \boxed{\text{B. La solución es todos los números reales.}} \]
