Answer:

Constant: A constant can be defined as a fixed value, which is used in algebraic expressions and equations. A constant does not change over time and has a fixed value. For example, the size of a shoe or cloth or any apparel will not change at any point.

In an algebraic expression, x+y = 8, 8 is a constant value, and it cannot be changed.

Variables: Variables are the terms which can change or vary over time. It does not remain constant, unlike constant. For example, the height and weight of a person do not remain constant always, and hence they are variables.

In an algebraic expression, x+y = 8, x and y are the variables and can be changed.
