9+105x
Consider the given expression.
| Property/Operation | Before | After |
|---|---|---|
| Commutative Property of Addition | ( 4+ 105x)+5 | ( 105x+ 4)+5 |
| Associative Property of Addition | (105x + 4 ) +5 | 105x+ ( 4 + 5 ) |
| Add Terms | 105x+( 4+5) | 105x+ 9 |
| Commutative Property of Addition | 105x + 9 | 9 + 105x |
Since 9 and 105x are not like terms, we cannot simplify further.
