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

Step 1: Factor out variable x.
x (y+12/2)=3

Step 2: Divide both sides by (y+12/2.

x(y+12/2)         3
------------- = ---------
   y+12          y+12
-----------      ----------
      2                2

Then your answer would be            6
                                              x=  ---------
                                                      y+12
