Question

Which property is not used to simplify the following equation?

Answer 1

Given:

`(x+5)\cdot2+7`

Solve with the property.

Sol:

`=(x+5)\cdot2+7`

Commutative property of multiplication then:

`=2(x+5)+7`

Use distribution property.

`=(2x+10)+7`

Associative property of addition

`=2x+(10+7)`

So Commutative property of addition not used.
