Answer 1

Answer:

Answer: A representation of the unknown value is said to be variable. Alphabets like a,b,c …..x,y, z, any of these are used as variables In Mathematics the value of one variable is often dependent on the value of other variables. Even though we have a single value to be found why to use a variable in place of an unknown value the reason is for the equation having more than one variable.Example 4y = 3x + 2.Examples of variables are age, income, expenses, etc which does not remain constant are said to be variables.
