Can someone please go over the solution to this problem step by step? The book's interpretation is a bit hard to follow.

Thank you

x = capacity of jug X
y = capacity of jug Y

(1/5)x = (2/3)y since equal amounts of water are in both and X is 1/5 full and Y is 1/3 full

to fill Y, we'd need to add another (1/3)y to it ...

but ... (1/3)y = (1/10)x per the above (divide both sides by 2)

so X has (1/5)x - (1/10)x = (1/10)x left
