Question 97903
Let the number of years =x
then x years ago....
kaylene was 30 - x
jessica was  22-x
But according to condition, 2*(22-x)=30-x
44-2x=30-x
44-30=-x+2x
14=x

So the answer is 14 years
Verify:
14 years ago.... kaylene was 30 - x =30-14=16
14 years ago.... jessica was  22-x =22-14=8
then 16/8 = 2 ok
