Mariana [72]

Las edades de Andrea y Alejandro son 40 y 16 años, respectivamente.

En esta pregunta debemos traducir el enunciado en ecuaciones algebraicas y resolver el sistema resultante. Tras una lectura cuidadosa tenemos el siguiente sistema de ecuaciones:

y = \frac{2}{5}\cdot x (1)

x + y = 56 (2)

Donde:

  • x - Edad de Andrea, en años.
  • y - Edad de Alejandro, en años.

A continuación, procedemos a resolver el sistema:

(1) en (2):

x + \frac{2}{5}\cdot x = 56

\frac{7}{5}\cdot x = 56

7\cdot x = 280

x = 40

Por (1):

y = \frac{2}{5}\cdot 40

y = 16

Las edades de Andrea y Alejandro son 40 y 16 años, respectivamente.
