Is this a possible gaussian elimination. It is asked in a genuine question for gaussian elimination btw.

2x + 3y = 5

6x + 9y = 15

As a matrix it looks like

2 3 |5

6 9 |15

But when you do: row 2- 3*row 1

you get 0 0 0 in the bottom row and now way of working out the x & y values......am i missing something here?
