La edad de juan es un año menos que la tercera parte de la edad de la madre. si dentro de 5 años, la edad de la madre sera 10 añ
koban [17]

Usando un sistema de ecuaciones, se encuentra que Juan tiene 12 años e su madre tiene 39 años.

<h3>¿Qué es un sistema de ecuaciones?</h3>

Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.

En este problema, las variables son:

  • Variable x: Edad de Juan.
  • Variable y: Edad de su madre.

La edad de juan es un año menos que la tercera parte de la edad de la madre, por eso:

x = \frac{y}{3} - 1

Dentro de 5 años, la edad de la madre sera 10 años mas que el doble de juan, por eso:

y + 5 = 2(x + 5) + 10

y + 5 = 2x + 20

Como x = \frac{y}{3} - 1:

y + 5 = \frac{2y}{3} + 18

3y + 15 = 2y + 54

y = 39

x = \frac{y}{3} - 1 = \frac{39}{3} - 1 = 13 - 1 = 12

Juan tiene 12 años e su madre tiene 39 años.

Morgarella [4.7K]

Answer:

Draining rate is at 1.5 gallons per minute

That would be y = 1.5g / x.

From the function or the equation, here is the answer.

The range would be all real numbers such that 0 ≤ y ≤ 40.
