SOLUTION: "Solve each system by substitution."
y=-4x+16
y=2x+4
I changed y=-4x+16 to -4x+y=16 then I put the bottom equation (y=2x+4) into that so:
-4x+(2x+4)=16 and got x=-6 so I put

Question 483997: "Solve each system by substitution."
y=-4x+16
y=2x+4
I changed y=-4x+16 to -4x+y=16 then I put the bottom equation (y=2x+4) into that so:
-4x+(2x+4)=16 and got x=-6 so I put that into y=2x+4 so y=2(6)+4 and got y=16 but I don't think it's right. (-6,16)

y=-4x+16
2x+4 =-4x+16
2x+4x =16-4
6x =12
x=12/6
x=2
------------
y=2x+4
y=2(2)+4
y=4+4
y=8
So x = 2 and y = 8 giving us the ordered pair (2,8)
