Multiply -3[4x+y=6].
This gets you -12x-3y=-18.
Add the two equations together to eliminate the y.
-12x - 3y = -18
+ 12x + 3y = 18
------------------------
0 = 0
This means that these are in fact the same line, therefore there are infinite solutions.

The answer is b because if you multiply 3 with m you get 3m and since -2 is a negative when you multiply it, it becomes -6
