Chapter 2: Q50. (page 105)

For the given expression, identify the terms, like terms, coefficients, and constant terms. Then simplify the expression. (Lesson 2.3)

7w-w+9-6w

Short Answer

Expert verified

Value of given expression is 9.

Step by step solution

01

Step-1- Terms and like terms

7w-w+9-6w

Parts of an expression that are added together are called terms

Therefore, the terms in given expression are 7w,-w,9,-6w.

The term which has the same variable part are called like terms

Therefore, the like terms in given expression are 7w,-w,-6w.

02

Step-2-Coefficients and constant terms

Number part of a term with a variable is called the coefficient.

Therefore, the coefficients in given expression are 7,-1,-6.

Term independent of any variable are called constants.

Therefore, the constants in given expression are 9.

03

Step-3-Solving given expression

7w-w+9-6w

On simplifying, we get

7w鈭�w+9鈭�6w=7w鈭�w鈭�6w+97w鈭�w+9鈭�6w=9

Therefore, the value of given expression is 9.
