Question 322312: Hi, Ive been given a question. "Twelve years ago Jack was five times as old as Jill. In three years time Jill will be half of Jack's age. What are Jack and Jill's present ages?"
I've tried heaps of different equations with no luck so far.
If Jack = y and Jill = x I have been using the following -
y = 5x - 12
x = y/x + 3
So I go x = (5x - 12)/x + 3
I've tried several others I just can't figure it out. Becoming really frustrating and a push in the right direction would be hugely helpful! :)
Thanks!
