Por lo tanto, el valor de x e y es 5, 8.

<h3>¿Qué es el método de sustitución?</h3>

El método utilizado para resolver el sistema de ecuación, en este el valor de una variable se sustituye de una ecuación a otra para encontrar la solución.

Está dado

(x+1)/3 -(y-1)/2 = 1                 -----1

7x -4(x+y) = 4                      ------2

Resolviendo la segunda ecuación

7x -4x-4y = 4

3x -4y = 4

3x = 4+4y

x = (4+4y) / 3

Sustituyendo este valor en la ecuación 1

2(x+1) - 3(y-1) = 6

2x +2 -3y+3 = 6

2x -3y = 1

2(4+4y)/3 - 3y = 1

8 + 8y - 9y = 3

-y = -5

y = 5

x = 24/3 = 8

Por lo tanto, el valor de x e y es 5, 8.
