5. 4x + y - 25

CONCEPT TO BE IMPLEMENTED

Algebraic expressions :

A combination of constants and variables , connected by four fundamental arithmetical operations i.e addition , subtraction , multiplication and division is called an algebraic expressions

Terms :

Various parts of an algebraic expression , which are separated by + or – are called terms of the algebraic expression

Coefficients :

In a term of an algebraic expression the numerical factor of a term is called coefficients and any of the factors with the sign of the term is called coefficient of the product of the other factors

EVALUATION

1. 20 + m

Variable is x and constant term is 20

2. 12(x - y)

Variable are x and y

Constant term is 0

3. 3x + 2 + 3y

Variable are x and y

Constant term is 2

4. 15b - 20 + 7

Variable is b

Constant term is - 20 & 7

5. 4x + y - 25

Variable are x and y

Constant term is 25
