Tradition.
it doesnt matter which letter is used it could be n,d,w, etc
but x and y is just more popular
The answer to the equation y x - x a would be x(y-1). When letters are used in a math expression, this is a form of math called Pre-Algebra or Algebra.
In algebra we consider x,y and z are variables.
y=x-2 y=x+4
It is simply: yx which in algebra means y times x
Given two numbers, x and y their difference is |x - y|. |x - y| = x - y if X ≥ y and |x - y| = y - x if x < y
The answer to the equation y x - x a would be x(y-1). When letters are used in a math expression, this is a form of math called Pre-Algebra or Algebra.
In algebra we consider x,y and z are variables.
They are unknowns, or placeholders. The actual x and y are not significant. You could use any letter that you wanted, but the x and y are traditionally used so that everyone knows what they are.
It equels 10* * * * *The answer depends on the values of x and y.
y=x-2 y=x+4
It is simply: yx which in algebra means y times x
x is a letter often used as a variable. It can be in the range or the domain. However, in elementary algebra, the variable x is most often used for the domain and f(x) =y for the range.
Given two numbers, x and y their difference is |x - y|. |x - y| = x - y if X ≥ y and |x - y| = y - x if x < y
x+y=2 x-4=4
() x=y(x)xy(x)(x)=() (). X=
well u have to find out the values of x and y first to answer it! =)
Any letter in the alphabet can be used to represent a variable in algebra.
