The correct answer is:  [A]:  "step 1" . 
________________________________________________________

Note the "distributive property" of multiplication:
________________________________________________________

 a(b + c)  =  ab + ac ;  AND:

 a(b − c)  =  ab − ac .
________________________________________________________

So:  Given:  " 2(x + 3) = 8 " ;  

Using the "distributive property" of multiplication:

   " 2(x + 3)  =  (2*x)  +  (2*3) ; 

      =  2x + 6 ; 

and rewrite as:  " 2x + 6 = 8 " ;  

which is:  "Step 1" ;  which is:  "Answer choice:  [A]:  "Step 1" .
