In 2005, carl = c
In 2005, jennifer = 2C
If he was born in 1984, in 2005 he is 21..
c = 21
2c = 2(21) = 42
So in 2005, Jennifer was 42.
2005 - 42 = 1963
She was born in 1963.

x= year´s jennifer born
y= years old of Carl
2005-x=2y
2005-1984= y
y= 21
=> 2005-x = 2(21)
2005-42 = x
x= 1963
2007- 1963 = 44
If Jennifer born in 1963, she has 44 years old.
