Chapter 2: Q. 120 (page 229)

In the following exercise, solve each equation requiring simplification.
$- 12 (d - 5) - 29 = 43$

Short Answer

Expert verified

On simplifying, we get $d = - 1 .$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenequationis - 12 (d - 5) - 29 = 43. \\ Wehavetosimplifythegivenequation. \end{array}$

Step 2. Simplify

$\begin{array}{l} Now, \\ \Rightarrow - 12 (d - 5) - 29 = 43 \\ \Rightarrow - 12 d + 60 - 29 = 43 [Simplifyeachside] \\ \Rightarrow - 12 d + 31 = 43 \\ \Rightarrow - 12 d + 31 - 31 = 43 - 31 [Subtract31fromboththesides] \\ \Rightarrow - 12 d = 12 \\ \Rightarrow \frac{- 12 d}{- 12} = \frac{12}{- 12} [Dividebothsidesby - 12] \\ \Rightarrow d = - 1 \end{array}$
