The choice to use variables like x and y in algebra is arbitrary. They are simply placeholders that can represent any unknown quantity or value. Using variables allows mathematicians to generalize problems and find solutions that work for a wide range of scenarios. The letters x and y are commonly used due to historical reasons and tradition, but any other letter or symbol could be used as well.
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.
x+y
It is simply: yx which in algebra means y times x
y=x-2 y=x+4

x+y
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.
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.
It equels 10* * * * *The answer depends on the values of x and y.
It is simply: yx which in algebra means y times x
y=x-2 y=x+4
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
well u have to find out the values of x and y first to answer it! =)
() x=y(x)xy(x)(x)=() (). X=
