2x+3y=2

6x+9y=0

Jul 24th, 2015

2x + 3y = 2

6x + 9y = 0

Taking 3 common from send equation then

2x + 3y = 2

3(2x + 3y) = 0

So

2x + 3y = 2

2x + 3y = 0

Now subtracting second from first, we get

2x + 3y = 2

- 2x - 3y = 0
----------------
0  +  0 = 2

0 = 2

Which is not possible. So it has no solution.

Or

there is some kind of mistake in the question.
