Chapter 2: Q. 233 (page 252)

In the following exercise, solve each linear equation.
$21 (y - 5) = - 42$

Short Answer

Expert verified

The solution of the equation is $y = 3 .$

Step by step solution

Step 1. Given information

The given equation is $21 (y - 5) = - 42$ .

We have to solve the given equation.

Step 2. Solving the given equation

$\begin{array}{l} Now, \\ \Rightarrow 21 (y - 5) = - 42 \\ \Rightarrow 21 y - 105 = - 42 [UsetheDistributiveProperty] \\ \Rightarrow 21 y - 105 + 105 = - 42 + 105 [Add105boththesides] \\ \Rightarrow 21 y = 63 \\ \Rightarrow \frac{21 y}{21} = \frac{63}{21} [Divideboththesidesby 21] \\ \Rightarrow y = 3 \end{array}$
