          -15x+6+6y-36+12y
          collect terms after multiplying through by -1:
          15x-6-6y+36-12y
          15x-18y+30
          divide through by 15
          x-18/15y+2 18/15 can be reduced to6/5 by the common factor 3
          x-6/5y+2
          0r 5x-6y+10 multiplying through by 5.
