Question

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

$5p+3=7(p=-3)$

Answer 1

Given , $5p+3=7$

Now, put $p=-3$

Here,

$$\begin{gathered} L.H.S.=5p+3 \\ =5\times (-3)+3 \\ =-15+3 \\ =-12 \end{gathered}$$

$R.H.S.=7$

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

Therefore, $p=-3$ is not a solution of given equation
