$b = -0.222...$

$-9(b) = 2$

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

$2 / -9 = b$

So

$2 / -9 = -0.222 ...$

$b = -0.222...$

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

$b = -0.dot(2) = -0.bar(2)$

$-0.bar2$

$-9b=2$

solve:

$=2/-9=-0.bar2$

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