Question

x *2011 -x= 2011 * 2009 +2011

 

Answer 1

x *2011 -x= 2011 * 2009 +2011

=> x*(2011-1)=2011*(2009+1)

=>     x*2010=2011*2010

=>            x=2011

Answer 2

x x 2011 - x = 2011 x 2009 + 2011

x x ( 2011 - 1 ) = 2011 x ( 2009 + 1 )

x x 2010 = 2011 x 2010

x x 2010 = 4042110 : 2010

x             = 2011
