I need help finding out what Y and X are in this equation 2X 3Y=6 but in a tee chart its for my notes but I'm having a hard time figuring it out I need three of the X and three of the Y please help me I need it for my note that I need to turn in, a couple of days until I need to turn it in!

I need help figuring out what Y is in the equation Y=4 I need it for my notes which I have to turn in a couple of days but I need it in a tee chart and I need three of what Y could be.

Here's some information about how to construct a "tee chart": Graphing Linear Equations: Making a T-Chart (http://www.purplemath.com/modules/graphlin.htm)

In your case you need to convert the equation from 2x+3y=6 to a form where y is by itself. Starting wth:
2x + 3y = 6, first subtract 2x from both sides:

3y = 6 - 2x

Then divide through by 3:

y = 2 - (2/3) x

Now construct your Tee chart and pick some values of x to use. It's always good to find what happens at x = 0, and also solve for the value of x where y=0. Then pick a few more points and see what you get.

Oh so on that one X would be 2 then Y would be 3?

Not quite. If x = 2 you get:

y = 2-(2/3)x = 2 - (2/3)2 = 2 - 4/3 = 2/3

Um I'm sorry I don't understand oh by the way this is linear equation's sorry don't know if I spelled that right!
