y can be anything at all, as it represents an independent variable. In a concrete example, one may have x representing a family size, but y could be anything - even something totally unrelated, like how many elephants there are! One of the many purposes of graphing x with y is to demonstrate a relationship between them that can then be described as a function, which hopefully provides insight into the world.

If x plus y equals 3 and yx equals 2 then y is equal to what?
If x+y = 3 and y times x = 2 then y = 1.
X - 2y equals -4 and 2x - y equals 1 what does x and y equal?
X = 2 and Y = 3.
What is 2x-y equals 5 when x equals 4?
If x=4... then 'y' MUST equal 3 !
X plus 2y equals 4 y equals 2x plus 7 what does x and y equal to?
x = -2 and y = 3
The only integer n for which n equals x to the y power equals y to the x power for x is not equal to y?
This is definitely false; if x=2 and y=3, x to the y power is 8, but y to the x power is 9, which are not equal.
What does y equals x - 3 equal?
that is an equation of a line with a slope of 1 and y-intercept of -3 and x-intercept of 3
What does '6x-2y' equal when x equals 8 and y equals 3?
the answer is 42
Does 4 equal x plus y if x is 3 and y is 0.2 plus 0.8?
No it equals 6 because x and y equal 1 in themselves
If x equals 3 and 3 equals y then?
x=y
If y equals x and y equals 6-x what is the solution?
y=x y=6-x Set the two equations equal to each other to yield a solution: x=6-x 2x=6 x=3 x=3 will satisfy both equations, that is plugging in x=3 will give the same value for y y=(3)=3 y=6-(3)=3
If y equals 3x and 3x equals 12 what does y equal?
y = 12. It's the transitive property. y = 12 = 3x.
If and x equals -18 find y?
if and x equal -18 find y -18 * 1/3 = -6
