Answer :

To prove: Set of given lines are inconsistent.

Given set of lines are : -

x + 2y = 9

2x + 4y = 7

Converting the following equations in matrix form,

AX = B R2 – 2R1 Again converting into equation form, we get

x + 2y = 9

0x + 0y = - 11

0 = - 11

which is not true

x + 2y = 9

2x + 4y = 7 are inconsistent.
