What is the value of m if the following systems of equations has no solutions?

i) 2x+6y=3

ii) 4x+2my=6

2x + 6y = 3 / * 2;

4x + 12y = 6;

We compare with 4x + 2my = 6;

If 12 = 2m (m = 6), we have an infinite solution;

If 12 isn't 2m (m isn't 6), we have one solution;

For example, m = 5 (it isn't 6); we solve the system of equations;

2x = 3 - 6y;

4x = 6 - 12y;

(6 - 12y) + 2*5*y = 6;

6 - 12y + 10y = 6;

-2y = 0;

y = 0; x = 3 / 2;

In conclusion. there is no value of m for the system of equations has no solution!
