easy

Check the solutions of the equation $x -2y = 4$ and which are not : $(4,\,0)$

Option A

Option B

Option C

Option D

Solution

$(4,\,0)$ means $x=4$ and $y=0$

Putting $x=4$ and $y=0$ in $x-2 y=4,$ we get

L.H.S.$= 4-2(0)=4-0=4$

But R . H.S $=4$ $\therefore $ L.H.S . $=$ R.H.S

$\therefore $ $(4,\,0)$ is a solution.
