Which of the following shows the Commutative Property of Addition? (4 + 3) + x = (3 + 4) + x ab = ba r + (s + t) = (r + s) + t n + 0 = n

Commutative says you can add or multiply in any order

basically goes like this

a+b=b+a or

ab=ba

so what we need is something where the order change, nothing else

first one: (4+3) + x = (3+4) + x, the order changed, correct

2nd

ab=ba, this is not addition

3rd

r + (s+t) = (r+s) + t this is associative property

4th

n+0=n

this is zero addition property

answer is first one
