Answer 2

Answer:

Hence the value of p$=-2$

Step-by-step explanation:

In accordance with the information provided in the question,

We have find the value of the supplied expression in the above question.

Given the data in question  21 + 6p = 9​

We have find the value of p in above equation

Hence, for solving the above equation, we will solve it by separating the like terms at one side.

So, we will shift 21 from LHS to RHS the sign will change from positive to negative,

As we get,

$21+6p=9\\6p=9-21\\6p=-12$

Divide both side by 6 we get,

$\frac{6p}{6} =\frac{-12}{6} \\p=-2$
