Chapter 1: Q15 (page 10)

Find the value of the variable.
$- 9 b = 2$

Short Answer

Expert verified

The value of the variable is $b = - \frac{2}{9}$ .

Step by step solution

Step 1. Divide by 9.

To find the value of variable b in the equation $- 9 b = 2$ , divide both sides of the equation by 9.

$- \frac{9 b}{9} = \frac{2}{9}$

Step 2. Simplify the equation.

To further simplify, cancel the common factors of 9 on both sides.

$- b = \frac{2}{9}$

Step 3. Multiply by -1.

In order to obtain b, multiply the equation $- b = \frac{2}{9}$ from both sides $- 1$ .

$\begin{array}{l} - b \times (- 1) = \frac{2}{9} \times (- 1) \\ b = - \frac{2}{9} \end{array}$

Step 4. Verify the value.

In order to verify the value of b, substitute $- \frac{2}{9}$ for b into the equation $- 9 b = 2$ .

$\begin{array}{l} - 9 \times (- \frac{2}{9}) = 2 \\ 2 = 2 True \end{array}$

Hence, the value of the variable is $b = - \frac{2}{9}$ .
