Answer 2

Option 4 - The expression is equivalent to 12 + 3 + (-7) because of the commutative property.

Explanation:

To find : Which statement is true about the expression
`12 - 7 + 3`?

Solution :

Associative property states that,
`a+(b+c)=(a+b)+c`

Commutative property states that,
`a+b=b+a`

By definition of properties we conclude that option 4 applies the correct property i.e. commutative.

As
`12 - 7 + 3=12+3+(-7)`

`5 + 3=15-7`

`8=8`

Therefore, The expression is equivalent to
`12 + 3 + (-7)` because of the commutative property.

So, Option 4 is correct.
