Answer 1

{[(x-3):2005+2005]:2006+2006}:2007+2007=2008
{[(x-3):2005+2005]:2006+2006}:2007=2008-2007
{(x-3):2005+2005]:2006+2006=2007×1
{(x-3):2005+2005]:2006=2007-2006
(x-3):2005+2005=2006×1
(x-3):2005=2006-2005
x-3=2005×1
x=2005+3
x=2008

Answer 2

{[(x-3) : 2005 +2005] : 2006 + 2006} : 2007 = 2008 - 2007 
{[(x-3) : 2005 +2005] : 2006 + 2006} : 2007 = 1 
{[(x-3) : 2005 +2005] : 2006 + 2006} = 1 x 2007
{[(x-3) : 2005 +2005] : 2006 + 2006} =  2007
[(x-3) : 2005 +2005] : 2006 = 2007 - 2006 
[(x-3) : 2005 +2005] : 2006 = 1
( x- 3) : 2005 + 2005 = 1 x 2006 
(x - 3) : 2005 + 2005 = 2006
( x - 3) : 2005 = 2006 - 2005 
( x - 3) : 2005 = 1 
x - 3 = 2005 x 1 
x - 3 = 2005 
x = 2005 + 3 
x = 2008
