y = -1 and x = -3
x = 11 y = 16
y=16 x= -4
x = y = 0 ?
16
y2 +8y + 16 = 0 can factor to (y+4) (y+4) = 0 so y+4 = 0 so y = -4
y = -1 and x = -3
x = 11 y = 16
4x+4y=16 y=5 4x+ 20=16 4x=-4 x=-1
y=6x-16 y=-2x+8
x = 14
x+ySince x=4, we can replace the x with a 4:4+ySince y=12, we can replace the y with a 124+12 = 16
16. Because if y=8 then the question becomes 8+8. Which equals 16.
They are expressions.
x = 0 and y = 4
y=16 x= -4
