NO. You cannot subtract 3x from 6, since they are NOT like terms. 
You can think of it as the 6 does not have an x term, but in 3x, there is an x term.

Answer:  When "x = 1" ;  "2(6-3x) + x"  DOES EQUAL "2(3x) + x" .
___________________________________________________

2(6-3x) + x = 12 - 6x + x  = 12 - 5x ;

2(3x) + x = 6x + x = 7x ;

Does:  12 - 5x = 7x ?

Add "5x" to each side of equation:

12 - 5x + 5x = 7x + 5x ;

to get:

12 = 7x + 5x ;

12 = 12x ; 

Divide each side of the equation by "12" ; 

12 / 12 = 12x / 12 ; 

to get:  1 = x ;  ↔ x= 1 ;
