SOLUTION: This question is about the Multiplication Property of Equality.
x/-9=-3
-9(x/-9)=-9(-3) How does the -9 outside of the ( ) reduce (x/-9) to x? Shouldn't it be -9(-9)=81?

x=27 Answer by Edwin McCravy(20054) (Show Source):
How does the -9 outside of the ( ) reduce (x/-9) to x?
Shouldn't it be -9(-9)=81?
No, because the is the same thing as the fraction
So it's the same as
And then the -9 in the the numerator cancels with the -9
in the denominator, like this:
And then we only have
which is just x
