Con un sistema de ecuaciones, tiene-se que:

  • Cada pera cuesta $1.
  • Cada manzana cuesta $3.

--------------

  • Usando la información dada en el texto, se construye un<em> sistema de ecuaciones</em> para encontrar el precio de cada pera e de cada manzana.
  • Yo diré que el precio de cada manzana es x y de cada pera es de y.

--------------

  • <u>La compra de 6 manzanas y 8 peras cuesta $26</u>, lo que significa que una de las ecuaciones es:

6x + 8y = 26

  • <u>Cada manzana cuesta lo triple de cada pera</u>, lo que significa que la outra ecuacione es:

x = 3y

--------------

Aplicando esta relacion en la primera ecuación, se encontra el precio de cada pera.

6x + 8y = 26

6(3y) + 8y = 26

26y = 26

y = \frac{26}{26}

y = 1

Cada pera cuesta $1.

--------------

Para cada manzana:

x = 3y = 3(1) = 3

Cada manzana cuesta $3.
