Chapter 5: Q3. (page 220)

Solve the equation. Check your solution.
$- 9 p = 81$

Short Answer

Expert verified

The solution of equation is $p = - 9$

Step by step solution

Step 1. Given information

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

Step 2. Calculation

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

- 9

Therefore,

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

Check:

Put $p = - 9$ in the given equation

$\begin{matrix} - 9 \times - 9 = 81 \\ 81 = 81 \end{matrix}$

Therefore, Left hand side =Right hand side

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