 why do we use variables such as (n,m,a,x )e.t.c. in algebra

if we need to find a particular value,we replace it temporarily as x and solve for it.

We add variables such as x, y, z , a, b ,c etc. to find a particular but undefined value that can vary.
  • -3
Because they do not have any fixed value.
  • -2
we add variables to find a particular and undefined value that can carry
  • -2
Because if we need to find a fixed value , we can replace it as a variable (such as x) and solve it.
  • -3
We use variables in integers because variables and do not have value so we use that
  • -3
it is used to tell indefinet value
  • -3
we use  variables to define numbers or mathematical symbols so that they can vary
  • -3
because it is a variable which is used in algebra

Though it can be anything, you often see letters like x or y as variables in algebraicequations. The other parts of equations include constants, which are fixed quantities that cannot change, and coefficients, which are numbers that multiply a variable.

we use letters instead of numbers in algebra because, if we need to represent a uknown number it can be represented using numbers.

BECAUSE THE ARE NOT HAVING ANY FIX VALUE LIKE, 
                                           
                                                   X = 3 , 4, 5 OR ANY OTHER NUMBER IT CAN BE

We use letters(variables) because algebra is all about variables and constants. So, to represent any value we can use letters or variables such as a, b, c, etc.
  • 0
because the algebra is of x ,y ect which means no fxied value

We use variables in place of the values which we don't know.

Because they are variable and can take up any number.

Hi Naman,
We use variables like x, y, etc to represent some numbers which are not known to us.It can be any number like 1,2,3,etc.
These alphabetical letters are not constant number.
    Hope it helps you.
Thank you!!

Though it can be anything, you often see letters like x or y as variables in algebraic equations. The other parts of equations include constants, which are fixed quantities that cannot change, and coefficients, which are numbers that multiply a variable.

p is used for the variable price and q is used for the variable quantity. An expression such as 4x3 is a variable. It can assume different values because x can assume different values. ... A monomial is an algebraic expression that iseither a numeral, a variable, or the product of numerals and variables.

WE USE VARIABLES IN ALGEBRA TO REPRESENT QUANTITIES THAT ARE NOT FIXED
IF YOU UNDERSTOOD GIVE ME HELPFUL VOTE

As the equation is not solved yet variables such (n,m,a,x) are kept in place of numbers to solve the equation. Keep in mind a variable does not have a fixed value

Because everytime we calculate algebra equations , variables keep on changing that means variables can be any number in algebra , thats the reason we use letters to determine variables
  • 0
because it is the unknown quantity
  • 0
Variables are use to find the unknown quantity or value.
For example:
21+no.= 54
Sol- Let number =x
A.T.Q
=21 + x = 54
= x = 54 - 21
= x = 33
Thus, number = x = 33


Hope this will help you........

'Algebra' , a broad part of mathematics , is where variables are used mostly to represent certain terms in an equation . ... ' Variables ' are used to represent certain unknown values. x, y, z and many other letters of English alphabet , also Greek alphabet is used . These represent the unknown terms/values .

Because if we use numbers the value of only that number will be recognized

in less words algebra is a number form in which number value in not there or not specific, and to show or represent them on any book or device screen we use variables 
hope this help you :)

Because variables can be any letter of the English Alphabet. Not only n, m, a, x but we can use any letter of the English Alphabet.

Hello there, Naman Aggrawal.

We use variables in equations and expressions to replace an unknown numbers.
The definition of a variable is- An algebraic letter used in place (replaces) a unknown number or quantity. For example, an example of an equation is a + c= b  and bd-ds (when 2 variables are put together they are being multiplied). These 2 examples or of an equation and of an expression using variables.

Hope this helps,
have a great day.

To represent any unknown number variables are used but A B and C are considered as constraints not variable
