Atención, no es compatible indeterminado, usando el método de Gauss no llegamos a una ecuación del tipo 0 = 0 o, estudiando los rangos, el rango de la matriz asociada es 3. <br />

Atención, no es incompatible. Si se tratara de un sistema incompatible, usando el método de Gauss llegarías a una expresión imposible, a una igualdad que no sea nunca cierta o bien a que los rangos de la matriz asociada y de la matriz ampliada son diferentes. <br />
