3x+2y=4 --------- equation (1)

-6x-4y=-8 --------- equation (2)

Multiply equation 1 by2 and equation 2 by negative one.

2(3x+2y=4) = 2 (4) ------------> 6x + 4y = 8

-1(-6x-4y)=(-1)-8 --------------> 6x + 4y = 8

Since both equations represent same equation there is no solution.

The system cannot be solved because it is independent.
