Ravens

On two trees sitting 17 ravens. If 3 ravens flew from first to second tree and 5 ravens took off from second tree then the first tree has 2 times more ravens than second tree. How many ravens was originally on every tree?

Result

a =  11
b =  6

Solution:


a+b=17
a-3 = 2*(b+3-5)

a+b = 17
a-2b = -1

a = 11
b = 6
