a) Hace diez años las edades de Juan y Diego sumaban 36 años. Ahora Juan tiene el triple de la edad de Diego. ¿Cuál es la edad de cada uno ahora?

Respuesta :

01-05-2021

Answer:

Juan: 42

Diego: 14

Step-by-step explanation:

(d - 10) + (j - 10) = 36

d + j -20 = 36

d + j = 56

j = 3d

d + 3d = 4d = 56

d = 56/4 = 14

j = 3d = 3(14) = 42
