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

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)
