Question 1191180
.


            This post came with no question, which makes me very sad 

            (as usual as I see such an inaccuracy and disrespect to the tutors).


            The short resume to this problem is as follows.



<pre>
(1)  The case a= 3 is special.


     If  a= 3 and b= 10, then there are infinitely many solutions.

                         In this case, the system is dependent.


     If a= 3 and b =/= 10, then there is NO solutions and the system is inconsistent.



(2)  If a =/= 3, then we have three independent equations;

                 the system is consistent and has a unique solution.
