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

Your answer should be “b” i truly hope i could ! good luck (:
