Question

Check whether the value given in brackets is a solution to the given equation or not:

$4x+3=5(x=-2)$

Answer 1

Given :- $4x+3=5$

Now, put $x=-2$

Here,

$$\begin{gathered} L.H.S.=4x+3 \\ =4\times (-2)+3 \\ =-8+3 \\ =-5 \end{gathered}$$

$R.H.S.=5$

⇒ $L.H.S.\ne R.H.S.$

Therefore, $x=-2$ is not a solution of given equation
