so first you have to isolate x so it would be: -3/4x=9
anonymous
  • anonymous
are you with me so far?
anonymous
  • anonymous
got that. now do I have to find a number 4 and 9 go into?
anonymous
  • anonymous
so then you still need to get x by itself right? so then you have to divide both sides by -3/4

i multiplied by -4/3 because when you divide by a fraction you just multiply by the reciprocal
anonymous
  • anonymous
what about the 9?
anonymous
  • anonymous
you divided 9 by -3/4
anonymous
  • anonymous
ohhhh 9x4/3=12
anonymous
  • anonymous
but its 9 * (-4/3) so the answer is -12
