Exercise 25 Page 27

11+3x

Practice makes perfect
Consider the given expression.

(2+3x)+9 We are asked to simplify this expression. We can use the Properties of Real Numbers in order to do so. Let's do it!

Property/Operation Before After
Commutative Property of Addition ( 2+ 3x)+9 ( 3x+ 2)+9
Associative Property of Addition (3x+2 )+9 3x+ (2+9 )
Add Terms 3x+( 2+9) 3x+ 11
Commutative Property of Addition 3x+ 11 11+ 3x

Since 11 and 3x are not like terms, we cannot simplify further.
