Anne was 5 times as old as Lyn 5 years ago. If Lyn will be half as old as Anne in 10 years, How old is Lyn now?
5 years ago:
Lyn ---- x
Anne -- 5x
Now:
Lyn = x+5
Anne = 5x+5
10 years from now:
Lyn = x+15
Anne = 5x + 15
x+5 = (1/2)(5x + 15)
2x + 10 = 5x + 15
-3x = 5
solution makes no sense, the question is bogus.
