Se vendieron un total de 430 boletos para la obra de teatro escolar. Los boletos eran o de adulto o de estudiante. Se vendieron
BartSMP [9]

Resolviendo un sistema de ecuaciones, veremos que se vendieron 250 boletos de adulto.

<h3>¿Cuántos boletos de adulto fueron vendidos?</h3>

Definamos las variables:

  • x = boletos de adulto vendidos.
  • y = boletos de estudiantes vendidos.

Se vendieron un total de 430 boletos, entonces:

x + y = 430

Y se vendieron 70 boletos de estudiante menos que boletos de adulto:

y = x - 70

Tenemos el sistema de ecuaciones:

x + y = 430

y = x - 70

Para resolverlo, podemos reemplazar la segunda ecuación en la primera:

x + y = 430

x + (x - 70) = 430

2x = 430 + 70 = 500

x = 500/2 = 250

Se vendieron 250 boletos de adulto.

Can someone answer these 2 questions for me?
Valentin [98]
For the first question x is equal to 4. You get this by adding 7x+2 and 3x and equal it to 42. And then solve algebraically so 10x+2=42
10x=40 so x equals 4
For the second question x is equal to 6.666 and y is equal to 9
You get this by getting x is to 10 as 4 is to 6 and you get y by 6 is to y as 4 is to 6
Hope this helps
