I have to assume that you want the answer in Spanish *but without using accents).
Usa las siguientes variables:
d = numero de habitaciones dobles
i = numero de habitaciones individuales
Por la primera premisa:
d + i = 180
Por la segunda premisa, los costos son tales que:
78d + 72i = 7839
Para resolver ese sistema podemos despejar una de las variables de la primera ecucacion y sustituir en la segunda:
i = 180 - d
78d + 72 (180 - d) = 7839
78d + 12960 - 72d = 7839
De aqui ya veo que va a dar un numero negativo para el numero de habitaciones dobles, asi que supongo que algun dato en el enunciado esta equivocado.
6d = 7839 - 12960 = -5121
=> d = -5121 / 6 = - 853.5
Al corregir los datos podras seguir el procedimiento que te he explicado para encontrar la solucion.
