Sea:
X = Primer Numero
Y = Segundo Numero
2X - 3Y = 5 (Ecuacion 1)
X + 2Y = -1 (Ecuacion 2)
En la ecuacion 2:
X + 2Y = -1
X = -1 - 2Y
Reemplazamos en la ecuacion 1
2(-1 - 2Y) - 3Y = 5
-2 - 4Y - 3Y = 5
-2 - 7Y = 5
-2 - 5 = 7Y
-7 = 7Y
Y = -7/7
Y = -1
Ahora:
X = -1 - 2(-1)
X = -1 + 2
X = 1
Los numeros son 1 y - 1
