Question

3+6+ x = x +6+3 A inverse property B identity property C commutative property D associative property

Answer 1

The equation \(3 + 6 + x = x + 6 + 3\) demonstrates the **commutative property** of addition. This property states that changing the order of the numbers you are adding does not change the sum.

So the correct answer is:

**C. Commutative property**
