Question

Solve the equation. Check your solution.

$-9p=81$

Short answer

The solution of equation is $p=-9$

Step-by-step solution

Step 1. Given information

Consider, the equation $-9p=81$given in the question

Step 2. Calculation 

To evaluate the equation $-9p=81$ provided, it is needed to divide each side of expression by

$-9$

Therefore,

$\begin{array}{c}-9p=81\\ \frac{-9p}{-9}=\frac{81}{-9}\\ p=-9\end{array}$

Check:

Put $p=-9$in the given equation

$\begin{array}{c}-9\times -9=81\\ 81=81\end{array}$

Therefore, Left hand side =Right hand side

Hence, the solution of equation is $p=-9$
