Chapter 1: Q14 (page 10)

Find the value of the variable.
$鈭� 3 b = 鈭� 9$

Short Answer

Expert verified

The value of the variable is $b = 3$ .

Step by step solution

Step 1. Divide by 3.

To find the value of the variable b in the equation $- 3 b = - 9$ , divide both sides of the equation by 3.

$鈭� \frac{3 b}{3} = 鈭� \frac{9}{3}$

Step 2. Simplify the equation.

To further simplify, cancel the common factors of 3 on both sides.

$\begin{array}{l} 鈭� \frac{3 b}{3} = 鈭� \frac{3 脳 3}{3} \\ 鈭� b = 鈭� 3 \end{array}$

Step 3. Multiply by -1.

In order to obtain b, multiply the equation $- b = - 3$ from both sides $- 1$ .

$\begin{array}{l} 鈭� b 脳 (鈭� 1) = 鈭� 3 脳 (鈭� 1) \\ b = 3 \end{array}$

Step 4. Verify the value.

In order to verify the value of b, substitute 3 for b into the equation $- 3 b = - 9$ .

$\begin{array}{l} 鈭� 3 脳 3 = 鈭� 9 \\ 鈭� 9 = 鈭� 9 True \end{array}$

Hence, the value of the variable is $b = 3$ .
