Question

Check if $(0,2)$ is the solution of the equation $x-2y=4$or not.

Answer 1

Checking if $x=0andy=2$ is the solution of $x-2y=4$or not:

We know that if the given value of the variable $x=0andy=2$ satisfies the given equation $x-2y=4$then that value will be the solution of the equation.

Step1:Putting the value of $x=0andy=2$in the given equation $x-2y=4$:

$$\begin{gathered} L.H.S \\ \Rightarrow 0-2\times 2=-4 \end{gathered}$$

$$\begin{gathered} R.H.S \\ 4 \end{gathered}$$

Step2: Comparing Both sides:

We can see that $L.H.S\ne R.H.S$

Hence, $x=4andy=0$ is not the solution of $x-2y=4$.
