Answer:
y=-3x+7
and x=-2y-16
rearrange both to get x and y on one side
So it becomes....
y+3x=7
x+2y=-16
if we want to cancel out the y terms first
( depends on your choice, I just chose y)
multiply the top equation by 2, and then subtract the equations
2y+6x=14
-x+2y=-16
5x=30
x=6
now substitute for find y(choose any equation you want out of the 2)
y+(3*6)=7
y+18=7
y=7-18
y= -11
