Chapter 2: Q41. (page 106)

Solve each equation. Then graph the solution set.
$4 - 3 |q| = 10$

Short Answer

Expert verified

The equation $4 - 3 |q| = 10$ has solution set as $q = - 2, 2$ and the graph of the solution set is:

Step by step solution

Step-1. Define absolute value equation.

For any real numbers a and b, if $|a| = b$ and $b \geq 0$ , then $a = b$ or $a = - b$ .

Step-2. Formulate case 1 when 4−3q=10.

Simplify the expression for q.

$\begin{matrix} 4 - 3 q - 4 = 10 - 4 \\ - 3 q = 6 \\ \frac{- 3 q}{3} = \frac{6}{3} \\ - q \times (- 1) = 2 \times (- 1) \\ q = - 2 \end{matrix}$

Step-3. Formulate case 2 when 4−3−q=10.

Simplify the expression for q.

$\begin{matrix} 4 - 3 (- q) - 4 = 10 - 4 \\ 3 q = 6 \\ \frac{3 q}{3} = \frac{6}{3} \\ q = 2 \end{matrix}$

Step-4. Plot the graph of the solution set.

From case 1 and case 2, $q = - 2, 2$ . Plot these values on the number line.
