Chapter 2: Q. 234 (page 252)

In the following exercise, solve each linear equation.
$- 9 (2 n + 1) = 36$

Short Answer

Expert verified

The solution of the equation is $n = - \frac{5}{2} .$

Step by step solution

Step 1. Given information

The given equation is $- 9 (2 n + 1) = 36$ .

We have to solve the given equation.

Step 2. Solving the given equation

$\begin{array}{l} Now, \\ \Rightarrow - 9 (2 n + 1) = 36 \\ \Rightarrow - 18 n - 9 = 36 [UsetheDistributiveProperty] \\ \Rightarrow - 18 n - 9 + 9 = 36 + 9 [Add 9 boththesides] \\ \Rightarrow - 18 n = 45 \\ \Rightarrow \frac{- 18 n}{- 18} = \frac{45}{- 18} [Divideboththesidesby - 18] \\ \Rightarrow n = - \frac{5}{2} \end{array}$
