These simultaneous equations have no solution.

If you multiply both sides of the first equation by #2# then you get:

#4x-2y=12#

The second equation gives us:

#4x-2y=-3#

SInce #12!=-3# these two equations cannot be satisfied simultaneously.

The graphs of these two equations are a pair of parallel lines and do not intersect:

graph{(4x-2y-12)(4x-2y+3) = 0 [-10, 10, -5, 5]}
