Answer:

Juan Pablo tiene 9 pavos y 9 chivos.

Step-by-step explanation:

En total son 18 animales, de los cuales algunos son pavos y otros chivos, por lo tanto tenemos:

18 = P + C     (1)

En donde:

P: representa a los pavos

C: representa a los chivos

Además tenemos que la suma de las patas de los chivos y de los pavos son 54:

54 = 2*P + 4*C    (2)

El 4 y el 2 se deben a las cuatro patas y a las dos patas de los chivos y de los pavos, respectivamente.

De la ecuación 1 tenemos:

P = 18 - C   (3)

Introduciendo P en la ecuación 2 nos queda:

54 = 2*P + 4*C

54 = 2(18 - C) + 4C

54 = 36 + 2C

C = 9

Ahora, introduciendo C=9 en la ecuación 3 tenemos:

P = 18 - C = 18 - 9 = 9  

Por lo tanto, Juan Pablo tiene 9 pavos y 9 chivos.

Espero que te sea de utilidad!
