which equation forms a pair of linear equations with 9x+12y=48 such that the system has no soulution?

Sagot :

Panoyin
9x + 12y = 48
9x - 9x + 12y = 48 - 9x
12y = 48 - 9x
 12        12
   y = 4 - 3/4x
9x + 12(4 - 3/4x) = 48
9x + 48 - 9x = 48
9x - 9x + 48 = 48
       0x + 48 = 48
              -48  -48
               0x = 0
                0     0
                x = 0
  9(0) + 12y = 48
      0 + 12y = 48
            12y = 48
             12     12
                y = 4
          (x, y) = (0, 4)
