Atención, mediante el método de Gauss debes llegar a una ecuación del tipo 0 = #t, que es una expresió imposible, que nunca es cierta.<br />

Muy bien, es un sistema incompatible ya que mediante el método de Gauss llegamos a una expresión imposible <span class="nolink">«math xmlns="http://www.w3.org/1998/Math/MathML"»«mn»0«/mn»«mo»=«/mo»«mi»#t«/mi»«/math»</span>, a una igualdad que no es nunca cierta. Por tanto, el sistema no tiene solución. <br />
