= and not = . Given x not = y , for x and y are two variables, does this mean every x not = y or just some x?

Question

Similarly, given x = y, where x and y are two variables, does this mean every x = y, or just some x = y?

Answer 1

Well, if x, and y are 2 variables, and you say that x = y. That means for a given value of y, the variable x must also have the same value. Say, if y = 3, then x must be 3 also.
It's like you say x = 4, or x = 5, i.e, you are assigning the value for x.

x <> y simply means that x is not equal to y, for any given y.
x <> 3 means that x can take any value, but NOT 3.


The equal sign has a different meaning if x, and y are functions (say, of t): x(t), and y(t). At that times, it depends on what the problem asks you to do.
If it says, solve for t in the equation x(t) = y(t); then it means that x(t) = y(t) can hold for some t, all t, or it doesn't hold for any t, and your task is to find the t value so that x(t) = y(t).

Answer 2

2. because of the fact the x term is on the left of the = sign. the y term is to the main appropriate of the = sign and that's believed to be 0. additionally, while a damaging type is squared, it is going to become advantageous. So x ought to = +4 or -4. Squaring the two one ends up in +sixteen. to alter it to 2 y-intercepts and one x-intercept, the x term would could = 0 on the main appropriate section and the y words would be to the left of the = sign. 3 & 4 are on your math e book. 5. devoid of algebra, shall we no longer sparkling up any issues previous addition and subtraction. very few issues are equipped devoid of algebra being in touch in some style. It became into with algebra (and trigonometry) that the Egyptians have been in a position to construct the pyramids to the precision that they are. Eratosthenes could no longer decide the size of the earth. The checklist would be longer that Y!A ought to enable.

Answer 3

1. at that situation x not= y
2. at that time x=y.


this all depends on the problem and values of the variables.

if i say x=1, y=1.
then always x=y.

if i say x=1, y=2
then no where x=y.

thats why they r called variables

Answer 4

FIRST QUESTION:
It means that within the framework of the problem being solved, X and Y will never be equal.

SECOND QUESTION:
It means that within the framework of the problem being solved, X and Y will always be equal.
