Question 1023594
Hi! First, I did this in my head-sort-of-way. I'm
Not sure if you had to solve this algebraically, but here you go:
Make a list of all possible solutions to add up to 31.
1,30 2,29 3,28------------------
14,17!! The older one is 17, while the younger one is 14.
They both add to 31, and are exactly 3 years apart!
I hope this helped you, and is it didn't, maybe
Somebody will respond with a much easier or faster way to do this!
