Proof & solve the equation for 6÷2 (1+2)

Answer
Let x= (1+2), will give 6÷2x

6/2x  =  3/x           OR       6/2x  =  6/(x+x)

Replace x with 3 will give:

6/2x  =  6/2(3)       OR       6/2x  =  6/((3+3) )
        =  1                                   =  6/6
                                                  =1

Does this equation's answer equals to 1 or 9 ?? It's confusing about...
