Question

If $p=-2$, find the value of: $4p+7$

Answer 1

Compute the required value:

From the given data $p=-2$

On substituting the value of $p$ in the given algebraic equation and simplifying we get

$4p+7$

$$\begin{gathered} =(4\times (-2\left)\right)+7 \\ =-8+7 \\ =-1 \end{gathered}$$

Hence the value of $4p+7$ is $-1$.
