    12y-21x=8, ie., y=(21/12)x+(2/3), ie., y=(7/4)x+(2/3). 16y=28x-184, ie., y=(7/4)x-(23/2). System has no solution since the 2 lines, are // an non-intersecting

  • 16y = 28x - 184

    4 * 4y = 4 * 7x - 4 * 46

    4y = 7x - 46

    4y - 7x = -46

    12y - 21x = 8

    4y - 7x = 8/3

    There are no solutions.  The lines are parallel.
