Check the solutions of the equation $x -2y = 4$ and which are not : $(2,\,0)$
Check the solutions of the equation $x -2y = 4$ and which are not : $(2,\,0)$
$(2,\,0)$ means $x=2$ and $y=0$
Putting $x=2$ and $y=0$ in $x-2 y=4,$ we get
L.H.S.$= 2-2(0)=2-0=2$
But R.H.S $=4$ $\therefore $ L.H.S . $\neq $ R.H.S
$\therefore $ $(2,\,0)$ is not a solution.
