system%286x%2B3y%2F2=-12%2C-4x-y=4%29

Multiply entire first equation by 2%2F3:

system%284x%2By=-8%2C-4x-y=4%29

Multiply the entire second equation by -1:
system%284x%2By=-8%2C4x%2By=-4%29

No matter if substitution or elimination method, No Solution.
The lines corresponding to the equations are parallel.
