11+3x
(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.
