Chapter 2: Q. 289 (page 253)

In the following exercise, solve each linear equation.
$0.2 (p - 6) = 0.4 (p + 14)$

Short Answer

Expert verified

The solution of the equation $0.2 (p - 6) = 0.4 (p + 14)$ is $p = - 34 .$

Step by step solution

Step 1. Given information

The given equation is $0.2 (p - 6) = 0.4 (p + 14)$ .

We have to solve the given equation.

Step 2. Solving the given equation

$\begin{array}{l} Now, \\ \Rightarrow 0.2 (p - 6) = 0.4 (p + 14) \\ \Rightarrow 0.2 p - 1.2 = 0.4 p + 5.6 [UsetheDistributiveProperty] \\ \Rightarrow 0.2 p - 1.2 - 0.4 p = 0.4 p + 5.6 - 0.4 p [Subtract 0.4 p fromboththesides] \\ \Rightarrow - 0.2 p - 1.2 = 5.6 \\ \Rightarrow - 0.2 p - 1.2 + 1.2 = 5.6 + 1.2 [Add1.2boththesides] \\ \Rightarrow - 0.2 p = 6.8 \\ \Rightarrow \frac{- 0.2 p}{- 0.2} = \frac{6.8}{- 0.2} [Divideboththesidesby - 0.2] \\ \Rightarrow p = - 34 \end{array}$

The solution of the equation is $p = - 34 .$
