lgbasallote · Answer

factor out the numerator and denominator...you'll be able to cancel something

anonymous · Answer

So far, I've come up with 2(-x+3) / 4(x-3)

anonymous · Answer

But not sure what to do now

lgbasallote · Answer

that's good! one trick you should know...

(-x+3) = -(x-3) if you pull out a negative sign..you can invert the operations inside a grouping symbol

anonymous · Answer

so the two would cancel out leaving 2 / 4 ?

anonymous · Answer

or 1/2

anonymous · Answer

is that right?

lgbasallote · Answer

yes! :DDD

anonymous · Answer

lgbasallote · Answer

oh wait...you pulled out a negative remember?

callisto · Answer

Hmm.. it should be a negative number instead of a positive one :(

callisto · Answer

6-2x/4x-12
= 2(3-x) / 4(x-3)
= -2(x-3) / 4(x-3)
= -2/4
= -1/2
