Answer:
x - y = 3
2x - 3y = 4
Igualación
Despejamos una de las incógnitas en cada ecuación e igualamos. (En este caso la x)
3y + 4
x = y + 3 x = ---------------
2
3y + 4
y + 3 = ---------------
2
2 (y + 3 ) = 3y + 4
2y + 6 = 3y + 4
se pasan las incógnitas a un lado y lo que cambia de lado se cambia de signo
3y - 2y = 6 - 4 ⇒ y = 2
sustituimos el valor de y en cualquiera de las dos para obtener el valor de x
x - 2 = 3 ⇒ x = 5
Solución
x = 5
y =2
