(y * x) - y = y * (x - 1)
you subtract x from both sides for both equations to get it in y= form. so... x+y=5 x+y-x=5-x y=5-x x+y=6 x+y-x=6-x y=6-x thanks:D but i meant with absolute value signs it was supposed to look like this : |x+y|=5 and |x|+|y|=6 ... but when i typed it in answers.com changed it
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
given: x - 4 = -y or, -y = x - 4 or, y = -(x - 4) or y = -x + 4 or y = 4 - x i.e. for x > 4, the equation x - 4 = -y is true.
If y varies directly as x and y is 18 when x is 24, then y is always three fourths of x. So if y is 15, then x is 20.
a variable (4 x y)
X and Y stand for the x and y of an ordered pair. You could plug in the coordinate for x.
The Y doesn't stand for anything. It is part of the word RAY. In fact, the X doesn't stand for anything either. They were called x-rays because the type of radiation was unknown at the time.

Slope-Intercept Form is y=mx+b. m=slope and b=y-intercept. The y and x stand for the x and y coordinates in an ordered pair (x,y).
Variables are letters that stand for numbers x=5 y=3 j=4 J+X = 9
X and Y do not stand for anything. They are merely letters that represent a variable in an algebraic equation. X is generally used as the first variable, and Y is used as the second variable, to differentiate the difference between two variables so one letter does not need to be used for two variables. In GRAPHS, they stand for the axis line. X is the horizontal axis, and Y is the vertical axis.
They are both letters of the alphabet
Nothing. They don't stand for anything. The are just the axis on a grid. The x-axis is the horizontle line (from left to right.) and the y-axis is the vertical line (up and down).

That is the value called the y intercept - value of y when x = 0 for example if y = 3x + 4 b = 4 and y = 4 when x = 0
