STEPS: Substitute Y=5-3x into 5x-4y=-3 Should look like this: 5-4x (5-3x)=-3 Distribute——> Simplified is 17x-20=-3 Add 20 to both sides to get 17x by itself -3+20 is 17 so how you should have 17x=17 Divide 17(x) to isolate the X.... X=1
SOLVING FOR Y Substitute x=1 into y=5-3x Should look like y=5-3(1) Solve it and Y=2
