Answer:
La cantidad de dinero
Celia tiene = x = 9.33 €
Quique tiene = y = 4.67 €
Step-by-step explanation:
Representemos la cantidad de dinero
Celia tiene = x
Quique tiene = y
Entre Celia y Quique suman 14 €.
x + y = 14
x = 14 - y
Si Celia tuviera 1 euro, tendría el doble de dinero que Quique.
Por lo tanto,
x = 2 años
Nosotros sustituimos
2y + y = 14
3 años = 14
y = 14/3
y = 4.67 €
x = 14 € - y
x = 14 € - 4.67 €
x = 9.33 €
Por lo tanto,
La cantidad de dinero
Celia tiene = x = 9.33 €
Quique tiene = y = 4.67 €
