It is given that:

4 + (x + y) = (4 + x) + y

As we know,

Commutative property is the property in which we can arrange the terms withouth changing the sign.

For an example:

a + b = b + c

In the given expression

4 + (x + y) = (4 + x) + y

The Commutative property is applied to rearrange the terms.
