Para resolver la desigualdad compuesta \( 3x + 4 \leq 2x + 8 \leq 2x + 6 \), primero desglosaremos la parte izquierda de la desigualdad \( 3x + 4 \leq 2x + 8 \). Restamos \( 2x \) de ambos lados: \( 3x - 2x + 4 \leq 8 \) Lo que simplifica a: \( x + 4 \leq 8 \) Restamos 4: \( x \leq 4 \) Ahora, resolvemos la parte derecha de la desigualdad \( 2x + 8 \leq 2x + 6 \). Al restar \( 2x \) de ambos lados, obtenemos: \( 8 \leq 6 \) Esto es falso, lo que indica que no hay solución que satisfaga esta parte de la desigualdad. Dado que la segunda parte de la desigualdad es inconsistente, concluiríamos que la solución global de la desigualdad compuesta es que no hay valores de \( x \) que satisfagan \( 3x + 4 \leq 2x + 8 \leq 2x + 6 \).
