Solve using substitution x=(3y+1) and x+4y=15
natka813 [3]

The solution is: x= 7 and y = 2

Step-by-step explanation:

Given equations are:

x = 3y+1\ \ \ \ Eqn\ 1\\x+4y = 15\ \ \ \ Eqn\ 2

Putting x = 3y+1 in equation 2 from equation 1

3y+1+4y = 15\\7y+1 = 15\\

Subtracting 1 from both sides

7y+1-1 = 15-1\\7y = 14

Dividing both sides by 7

\frac{7y}{7} =\frac{14}{7}\\y = 2

Putting y=2 in equation 1

x = 3(2) +1\\x = 6+1\\x = 7

Hence,

The solution is: x= 7 and y = 2

En un aeropuerto dos aviones A1 y A1 se acercan para aterrizar, si la ecuación de la trayectoria del primero es -x+2y-100=0, mie
liraira [26]

No hay solución en la que ambas trayectorias estén en la misma posición, puesto que no existe el riesgo de que sufran un choque entre ellos.

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

La trayectoria del primero es:

-x + 2y - 100 = 0

x_1 = 2y - 100

Para el segundo, tiene-se que:

-x + 200 + 2y = 0

x_2 = 2y + 200

Igualando los valores de x:

x_1 = x_2

2y - 100 = 2y + 200

0y = 300

No hay solución en la que ambas trayectorias estén en la misma posición, puesto que no existe el riesgo de que sufran un choque entre ellos.
