The question is phrased:
1st son gets 1000 + 1/7 of what is left of entire estate at that moment.
Then
2nd son gets 2000 +1/7 of what is left of entire estate at that moment.
estate = z
In other words the second son is getting: z-1000+1/7-2000+1/7...
Like this:
1. 1000+1/7x = 2000+1/7y
2. y = x-1/7-1000
New Equation:
1000+1/7x = 2000+1/7x(x-1/7x-1000)
1000+1/7x = 2000+1/7x(6/7x-1000)
1000+1/7x = 2000+6/49x-142.86
1/7x-6/49x = 2000-142.86-1000
1/49x = 857.14
x = 41999.86 or 42000.0000
Now back in the original equation:
1st son: 1000+1/7(42000.0000)=1000+6000=7000
42000-7000=35000
2nd son: 2000+1/7(35000.0000)=2000+5000=7000
35000-7000=28000
3rd son: 3000+1/7(28000.0000)=3000+4000=7000
28000-7000=21000
4th son: 4000+1/7(21000.0000)=4000+3000=7000
21000-7000=14000
5th son: 5000+1/7(14000.0000)=5000+2000=7000
14000-7000=7000
6th son: 6000+1/7(7000.0000)=6000+1000=7000
NOW NO MONEY IS LEFT.... THIS IS THE PROOF........
