6+(-4)= (-4)+6

There actually is no question here.

It is just a true statement.

6+(-4)= (-4)+6

But as Rosala has said the answer is 2.

so we'd solve this like 

6+(-4)= (-4)+6  (now to solve this , lets break it into two parts L.H.S ( Left Hand Side) and RHS (Right Hand Side) ]

LHS = 6+ (-4)          (and now out here we will change the plus and minus sign to just minus sign and then subtract them both simply)

= 6 - 4 

=2   ANSWER

and now we will solve RHS

RHS= (-4)+6           (here we just have to mopen the brckets of -4 and subtract)

= -4+6

= 2    ANSWER

so.......LHS is equal to RHS so the final answer would be

2=2 ANSWER 

i hope u've understood by now but if not then pls be free to ask!

hope this helps!

But Melody this is a question!ive solved many like this!this isnt a true statement either!her we were to determine IF this was a true statement or not and i have determined that yes this is a true statement by using the method of LHS and RHS so this is a question!

But it doesn't say "prove" Rosala, it is just a true statement.

yeah u can say that aswell!its just a true statement!

Rosala has treated this question like a proof.

And yes Rosala if it had been presented as 'prove' your answer would be 100% correct.

It is not wrong anyway - but there is not question here.  It is just a statement.    

(I've added this because Rosala has asked me to comment further)

I  can't say much more than this.  Sorry Rosala.
