Show that the following systems of linear equations are inconsistent: `2x-y=5,\ \ 4x-2y=7`

Explanation

We have given systems of linear equations `2x-y=5,\ \ 4x-2y=7`

As we know that the system of linear equation can be written in matrix form as `AX = B`

`implies A=|(2,-1),(4,-2)|`,`X=[(x),(y)]`,`B=[(5),(7)]`

Now find the determinant of `A`,

`|A|=[(2,-1),(4,-2)]`

`|A|=Delta=-4+4=0`

Now as `B=[(5),(7)]`

Then
