For which values of the constant a does the equationsystem have infinty many solutions and then doesn't any solutions exist. $ax _{1} +(a-1)x _{2}+(a-2)x _{3}=0$ $(a-3)x _{2}+(a-4)x _{3}=1$ $(a-5)x _{3}=0$ Well I know that the system has infinity many solutions when a=5 but what should I look for then searching for the values there no solutions exist?
