Check the solutions of the equation $x -2y = 4$ and which are not : $(1,\,1)$
Check the solutions of the equation $x -2y = 4$ and which are not : $(1,\,1)$
$(1,\,1)$ means $x=1$ and $y=1$
Putting $x=1$ and $y=1$ in $x-2 y=4,$ we get
L.H.S.$= 1-2(1)=1-2=-1$
But R . H.S $=4$ $\therefore $ L.H.S . $\neq $ R.H.S
$\therefore $ $(1,\,1)$ is a solution.
