change the sign on one of the equations and you can get rid of the y
Subtract second equation from first:- 2x+4y=-8 -(-3x)-(4y)=-2 ------------- 5x=-10 x=-10/5=2
Now put the value of 'x' in any equation & find 'y' :)
Can u do that from now???
y=-16 ?

and x=-2 ?
Wait I have done a mistake it's x=-2 2x+4y=-8
2(-2)+4y=-8 -4+4y=-8 4y=-8+4 4y=-4 y=-4/4=-1
so y=-1 ?
yes why not ;)
