1. 2(6x -6)=84        2. 8(x+3)=5(x-6)       3. -9n=27
    12x-12=84                 8x+24=5x-6              n=27/-9
      12x=84+12                8x-5x=-24-6            n=-3      
       12x=96                     3x=-30
         x=96/12                    x=-30/3
          x=8                           x=-10
