9+105x

Practice makes perfect
Consider the given expression.

(4+105x)+5 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 ( 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.
