Question

(2009 - x ) : 29 +32 = 100 

Answer 1

(2009-x) : 29 + 32 = 100

(2009-x): 29 = 68

2009-x = 68 x 29

2009 - x = 2001

x= 2009 - 2001

x=8

Answer 2

( 2009 - x ) : 29 + 32 = 100

( 2009 - x ) : 29 = 100 - 32

( 2009 - x ) : 29 = 68

  2009 - x = 68 x 29

  2009 - x = 1972

            x = 2009 - 1972

            x = 37
