seis manzanas y 8 peras cuestan $26. Cuánto cuesta xada pera y cada manzana sabiendo que cada manzana cuesta el triple de lo que

vodomira [7]

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 sistema de ecuaciones 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.

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

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

$6x + 8y = 26$

Cada manzana cuesta lo triple de cada pera, 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.
