Use Google/Textbook to find the definition of commutative property . Then if you do not understand that - comeback and tell us exactly where you are lost.

and what is commutative property?

If * is a function, then we say that it is commutative if a*b=b*a where a and b are real.

I disagree with that. The way you are using it, "*" is a "binary operator" not a function.

 

[eddybob123]

A binary operation is a function \(\displaystyle f:S\times S\to S\).

Associative Property of addition allows,
x+4+2 = (x+4)+2 <=== NOT HELPFULL

Associative Property of addition also allows,
x+4+2 = x+(4+2) <=== HELPFULL

So, x+4+2 = x+6

Yes, but "binary operation" is more precise and more relevant here.

The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"

So knowing this we can rewrite your problem as 4+2+x
4+2 can be simplified to 6 so your problem can be rewritten as 6+x
