Question

Tell whether x=$3$ is a solution of equation x-$2=0$

Answer 1

By substituting the value of x on Left Hand Side of the equation we get,

$$\begin{gathered} x-2 \\ =3-2 \\ =1 \end{gathered}$$

Here Right Hand Side is $0$

$L.H.S\ne$$R.H.S$

Hence x=$3$ is not a solution of the given equation.
