Solution

Claro, vamos a resolver el sistema de ecuaciones paso a paso.

Dado el sistema de ecuaciones:

  1. y=52x y = 5 - 2x
  2. 4x+3y=13 4x + 3y = -13

Primero, sustituimos la ecuación (1) en la ecuación (2):

4x+3(52x)=13 4x + 3(5 - 2x) = -13

Ahora, distribuimos el 3 en la ecuación:

4x+156x=13 4x + 15 - 6x = -13

Combinamos los términos semejantes:

4x6x+15=13 4x - 6x + 15 = -13 2x+15=13 -2x + 15 = -13

Restamos 15 de ambos lados de la ecuación:

2x=1315 -2x = -13 - 15 2x=28 -2x = -28

Dividimos ambos lados por -2:

x=14 x = 14

Ahora que tenemos el valor de x x , lo sustituimos en la ecuación (1) para encontrar y y :

y=52(14) y = 5 - 2(14) y=528 y = 5 - 28 y=23 y = -23

Por lo tanto, la solución del sistema de ecuaciones es:

(14,23) (14, -23)

La respuesta correcta es:

(14, -23)
