Question

Check whether the value of x given is a solution of the given equation or not:

$5x-3=6x+4$, $x=5$

Answer 1

For $x=5$,

$$\begin{gathered} L.H.S.=5x-3 \\ =5\times 5-3 \\ =22 \end{gathered}$$

$$\begin{gathered} R.H.S.=6x+4 \\ =6\times 5+4 \\ =30+4 \\ =34 \end{gathered}$$

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

Hence, $x=5$ is not a solution of the given equation.
