Una ecuación del tipo 0 = 0 no aporta información adicional y se debe eliminar. Entonces, una de las incógnitas pasa a ser una variable y las otras incógnitas dependen de su valor. Por tanto, la solución del sistema no es única y el sistema no es compatible determinado. El sistema tiene infinitas soluciones (una para cada valor de la variable).
Choice 2

Atención, si se tratara de un sistema incompatible habríamos llegado a una expresión imposible, a una igualdad que no es nunca cierta. La expresión 0 = 0 no es una expresión imposible sino una expresión que no aporta información, siempre es cierta.
