8
if you are asking what y equals heres what it is y=54+4 y=58
x=4 y=4
y=8 y = 2x y = 2(4) <-- substitute 4 for x y = 8 <-- this is your answer
To get y by itself you add 4 to the other side of the equals sign. y= 16+4 y= 20.
-1
Well, if 3x equals 12, then x equals 4. And if y equals 3x, then y equals 3 times 4, which is 12. So, y equals 12. Math can be a piece of cake when you break it down like that!

y=-10x-4
To get y by itself you add 4 to the other side of the equals sign. y= 16+4 y= 20.
y=-x+4
If: 3x+y = 4 and x+y = 0 Then: x = 2 and y = -2
x=4 y=x+3 y=4+3 y=7
y=4
