Show that each one of the following systems of equations is inconsistent.

6x + 4y = 5;


9x + 6y = 8.



To prove: Set of given lines are inconsistent.


Given set of lines are : -


6x + 4y = 5


9x + 6y = 8


Converting the following equations in matrix form,


AX = B



2R2 – 3R1



Again converting into equation form, we get


6x + 4y = 5


0x + 0y = 3


0 = 3


which is not true


6x + 4y = 5


9x + 6y = 8 are inconsistent.
