#b = -0.222...#

#-9(b) = 2#

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

#2 / -9 = b#

Thus

#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)#

To solve ( -9(b) = 2 ):

Divide both sides of the equation by -9 to isolate the variable ( b ): [ \frac{-9(b)}{-9} = \frac{2}{-9} ]
Simplify: [ b = \frac{2}{-9} ]
The solution is ( b = -\frac{2}{9} ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
