FranWell, darling, the answer is not going to magically appear out of thin air. You need to give me more information. Is there another equation or some context to this problem? I may be good, but I'm not a mind reader.
Solve for x:
3x - y = -9 is the same as 3x + 9 = y
Since you now know the equation for y you can plug it into the first equation:
3x - (3x + 9) = -9
After solving, you will also see that x cancels out and that -9 = -9.
Solve for y:
3x - y = -9 is the same as y/3 - 3 = x
Since you now know the equation for x you can plug it into the first equation:
3(y/3 - 3) - y = -9
After solving, you will also see that y cancels out and that -9 = -9.
The Answer:
There are actually two posibble answers:
1.) y = -9 and x = 0
If you plug the numbers in then you will get 3(0) + (-9) = -9
The answer is -9 = -9
2.) y = 0 and x = -3
If you plug the numbers in then you will get 3(-3) + (0) = -9
This will also give you the answer -9 = -9

How do you get y by itself in the equation 3x-6y equals 9?
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
3x - y equals 9 2x plus y equals 6?
3x-y = 9 2x+y = 6 Add both equations together: 5x = 15 x = 3 and y = 0
What is the slope intercept form of -3x-9 equals 3y?
-3x - 9 = 3y -x - 3 = y y = -(x+3)
How do you identify the y intercept of y equals 3x-6?
9
What is the answer for 3x - y equals 9?
-6
3x minus y equals 9 solve for y?
3x-y=9 y=3x-9
What does y equals 3x plus y and y equals x-9 equal?
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
How do you solve for y 3x-y equals 12?
-9
How do you get y by itself in the equation 3x-6y equals 9?
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
