Fiona y sus amigas fueron a una tienda de batidos. Pidieron tres batidos de fresa y dos batidos de proteínas por un total de $ 2
jeka94

Answer:

Un batido de proteínas cuesta $ 5,25.

Step-by-step explanation:

El sistema de ecuaciones descrito al final del enunciado coincide con lo descrito al comienzo del mismo, de modo que podemos concentraron casi exclusivamente en la resolución del sistema en cuestión, la cual se describe a continuación:

Este es el sistema a resolver:

x + 4\cdot y = 25,50 (1)

3\cdot x + 2\cdot y = 24,00 (2)

Donde x es el coste de un batido de fresa y y corresponde al coste de un batido de proteínas:

1) Despejamos x en (1):

x = 25,50 - 4\cdot y

2) Eliminamos x en (2):

3\cdot (25,50 - 4\cdot y) + 2\cdot y = 24,00

76,50 - 12\cdot y +2\cdot y = 24,00

3) Simplificamos y despejamos y:

10\cdot y = 52,50

y = 5,25

Un batido de proteínas cuesta $ 5,25.

Step-by-step explanation:

Use inverese operations to isolate variables ex. x+4=2

x times 2 = 6                                                            -4

/2                                                                               x=-2

x=3
