Listen to your teacher or read your math book.

is that (3/4)x? i'll assume so, as this is pretty basic.
3-(3/4)x = -6
-3 -3
-(3/4)x = -9
divide both sides by -3/4, or in other words, multiply by -4/3
x = (-9)(-4/3)
x= 36/3
x=12
*edit*
however, if it's 3 divided by 4x, then you do this:
3-(3/4x) = -6
-3 -3
-(3/4x) = -9
(3/4x) = 9
multiply both sides by 4x
3 = 36x
/36 /36
x = 3/36 = 1/12
x = 1/12
your notation wasn't clear, so it very well could be either case; thus, i've worked them both. good luck.
*re-edit*

I'm sure you'd be a great math tutor ... if you put a little planning into it, you could probably make it a lucrative venture ... years ago I knew someone who preped HS kids for SATs.

just noticed adfef's edit.
yes, adfef, if you have two negative signs and you're multiplying or divding one by the other, you cancel the negative signs out. be sure to take note of where parentheses and brackets are, as well as to remember the order of operations.
