Chapter 2: Q. 96 (page 229)

In the following exercise, solve each equation using the Division and Multiplication Properties of Equality and check the solution.
$- 24 = \frac{p}{- 20}$

Short Answer

Expert verified

On solving, we get $p = 480 .$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenequationis - 24 = \frac{p}{- 20} . \\ Wehavetosolvethegivenequationandthenverifytheresult. \end{array}$

Step 2. Simplify

$\begin{array}{l} Now, \\ \Rightarrow - 24 = \frac{p}{- 20} \\ \Rightarrow - 20 \times (- 24) = - 20 \times (\frac{p}{- 20}) [Multiplybothsidesby - 20] \\ \Rightarrow 480 = p \\ o r \\ \Rightarrow p = 480 \end{array}$

Step 3. Checking the result

$\begin{array}{l} Wehave, \\ \Rightarrow - 24 = \frac{p}{- 20} \\ \Rightarrow - 24 = \frac{480}{- 20} [Substitute p = 480] \\ \Rightarrow - 24 = \frac{- 24 \times (- 20)}{- 20} \\ \Rightarrow - 24 = - 24 \\ L.H.S = R.H.S \\ Henceverified. \end{array}$
