2x+3y=0 and x+2y=-1 <br> Solve by substitution
dmitriy555 [2]

Answer:

The solution of the given equations is (-3,2)

Step-by-step explanation:

<u>Step:1</u>

The Given equations are 2 x+3 y=0 .......(1)

                                          x+2 y-1 =0.........(2)

<u>Step 2:-</u>

Solving<u> </u>both equations by using substitution method

multiply equation (2) with number '2' ,  

2 x+4 y-2=0.......(3)

subtracting the equations (1) and (3) and cancelled 'x' terms

we get 3y-4y=0-2

y=2

<u>Step 3:</u>-

substitute y= 2 in equation (1) we get

2 x+3 y=0

2 x+3(2)=0

2 x=-6

x=-3

<u>Final answer</u>:-

The solution of the given equations is (-3,2)

Durante un frente frío, la temperatura Canadá bajó de 7°C a -5°C ¿Cuántos grados bajo la temperatura
Anton [14]

Answer:

Durante el frente frío mencionado en el ejercicio, la temperatura de Canadá bajó:

  • <u>12°C</u>.

Step-by-step explanation:

Para obtener la cantidad de grados que bajó la temperatura en el caso mencionado, debes primero identificar la disminución en los grados positivos, es decir, cuando los grados Celsius llegaron a 0°C:

  • Diferencia entre 7°C y 0°C = <u>7°C</u>

En la operación matemática, solo restante la cantidad de grados necesarios a la temperatura inicial (7°C) para que la temperatura quedara en 0°C, donde obtenemos una diferencia de 7°C, ahora identificas la cantidad de grados que se necesitan para que la temperatura pase de 0°C a -5°C:

  • Diferencia entre 0°C y -5°C = <u>5°C</u>

Recuerda que como ya estamos hablando de diferencia, no necesitas señalar si los grados son negativos, solo identificamos el número de grados Celsius entre esas temperaturas mencionadas, por lo tanto, al final sumas las dos diferencias halladas y esa será la diferencia total entre las dos temperaturas dadas:

  • Diferencia entre 7°C y -5°C = 7°C + 5°C
  • <u>Diferencia entre 7°C y -5°C = 12°C</u>

Por lo tanto, durante el frente frío mencionado, <em><u>la temperatura en Canadá bajó 12°C</u></em>.
