# How do you solve -9(b)=2?

May 6, 2018

$b = - 0.222 \ldots$

#### Explanation:

$- 9 \left(b\right) = 2$

So you know that something multiplied by $- 9 = 2$. That means that

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

So

$\frac{2}{-} 9 = - 0.222 \ldots$

$b = - 0.222 \ldots$

which you can write as $- 0.2$ with a dot or a line above the digit $2$.

$b = - 0. \dot{2} = - 0. \overline{2}$

$- 0. \overline{2}$
$- 9 b = 2$
$= \frac{2}{-} 9 = - 0. \overline{2}$
