from the looks of this your simply plugging in x and solving for y
8x-4y=-12; x=-3,-1,1
8%28-3%29-4y=-12; x=-3
%28-24%29-4y=-12; Add 24
-4y=12; divide by -4
y=-3; x=-3


8%28-1%29-4y=-12; x=-1
%28-8%29-4y=-12; add 8
-4y=-4; divide by -4
y=1; x=-1


8%281%29-4y=-12; x=1
8-4y=-12; subtract 8
-4y=-20; divide by -4
y=5; x=1
