Question

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

$-3p-2=10(p=-4)$

Answer 1

Given :- $-3p-2=10$

Now, put $p=-4$

Here,

$$\begin{gathered} L.H.S.=-3p-2 \\ =-3\times (-4)-2 \\ =12-2 \\ =10 \end{gathered}$$

$R.H.S.=10$

⇒ $L.H.S.=R.H.S.$

Therefore,$p=-4$ is a solution of given equation
