1/2 (3x - 4) = 1/3 (4x - 4)
     3/2x - 2  = 4/3x - 4/3
-------------------------------- dikali 6
      9x - 12  = 8x - 8
      9x - 8x  = -8 + 12
                x = 4
 
9]
   3x + 8 = 3 (4x - 1)
   3x + 8 = 12x - 3
3x - 12x = -3 - 8 
        -9x = -11
           x = -11/-9
           x = 11/9

maaf ga pake cara.
