Mwoop, hallo, back here with another question but I only just started so you probably don't know me but please still try your best to help moi :) Moses is twice as old as Methuselah was when Methuselah was one-third as old as Moses will be when Moses is as old as Methuselah is now. If the difference in their ages is 666, how old is Methuselah? OK geez that sounds complicated, but I bet the answer is "simple" *cough cough* If you can solve this by using KESA (key, equation, solution, answer) then not only will you get a (wait for it wait for it) a MEDAL!!! But also a brand new fan.thx

    Let x = current age of Moses y = current age of Methuselah `Moses will be when Moses is as old as Methuselah is now.` means that Moses is the younger person. So x < y and the difference in the ages is `y - x` (the larger is placed first to make the difference positive). The first part of this problem is very needlessly complicated. I don't know why they twisted things up that much. So I'm going to focus on the easier part first. `the difference in their ages is 666` tells us `y - x = 666`. Solve for y to get `y = x+666` ------------------------------------------------------- `Moses is twice as old as Methuselah was when Methuselah was one-third as old as Moses will be when Moses is as old as Methuselah is now` is a very complicated way of saying `Moses is as twice as old as Methuselah's past age when he was 1/3 of what he is now` So basically (current age of moses) = 2*(1/3*(current age of Methuselah)) (x) = 2*(1/3*(y)) x = (2/3)*y ------------------------------------------------------- Now plug in y = x+666 and solve for x x = (2/3)*y x = (2/3)*(x+666) 3*x = 3*(2/3)*(x+666) 3*x = 2*(x+666) 3*x = 2*x+2*666 3x = 2x+1332 3x - 2x = 1332 1x = 1332 x = 1332 So Moses is currently 1332 years old y = x+666 y = 1332+666 y = 1998 and Methuselah is currently 1998 years old.
