RoseWind [281]
To represent the opposite of this number, if it is positive nineteen, he would need to first take nineteen steps back to reach his original position which in this case represents zero. He would then need to take another nineteen steps backwards, to reach negative nineteen.

Simplify the ration expression
\frac{3x-6}{x-2}

start by seeing if anything in the numerator or denominator can be factored,
you should notice that you can factor out a 3 from 3x-6 in the numerator

when you do so, the result is
\frac{3 *(x-2)}{x-2}

now, since there is an x-2 in the numerator and denominator, they "cancel" out since

\frac{x-2}{x-2} =1
however, only when x \neq 2
since \frac{0}{0} \neq 1

when you cancel out the x-2, you're left with 3

hence, your answer is C
