Label equation 1 and equation 2,

Then 4y can be cancelled down from both, so we would do equation 1 plus equation 2,

Once you did equation 1 plus equation 2 you should have :

6x=-8
So X= -4/3

Then we would sub x into equation 2,

So it would be, 4/3+4y= -2

Y=-5/6


So final answer is

X = -4/3 Y= -5/6
