  • I don't know how to solve equations with variables on both sides! We have a test tomorrow!!!!
  • I can teach you how to do it.
  • Ok, so you take your problem and see what you're dealing with, we will start with an easy one.  3x+2 = 9x+4
  • 3x+2 = 9x+4     -3x      -3x         
  • Take 3x and subtract it to make it go across to 9x.
  • 3x+2 = 9x+4     -3x      -3x         2 = 6x+4 -4       -4
  • Now re right your problem and subtract 4 to make it go to the 2.
  • 3x+2 = 9x+4     -3x      -3x         2 = 6x+4 -4       -4 -2 = 6x  6     6 -3 = x
  • Once again re right your problem and divide it by 6. To get your answer of -3 = x
  • TEST DAY!!
