You will know because there are no other numbers that can go into both the numerator and denominator.
Variable is any letter used in an algebraic expression, and can vary (change form) to be any number, and one variable means the same number in any single algebraic expression. Usually algebra is simplifying the expression or equation until you know what the variable is equal to.
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.
umm I don't know
uh i really don't KNOW ok

An algebraic expression does not contain an equality sign. Acting is a form of "expression".

i don't know sori....... hehehehe
sorry, i do not know
Sorry, I Don't Know :))
you can use any letter as long as you know what it means and represents.
It is an algebraic expression. It is not an equation and so cannot be solved. You do not know what n is so it cannot be evaluated.
That is its simplest form
