A man left 3/7 of his money to his wife, 1/2 of the remainder to his brother, and the rest he divided equally among his three children. If each of his children received $400, how much did his wife receive?
starting with x,
3/7 went to wife, leaving 4/7
1/2 of that, 2/7, went to brother, leaving 2/7 for his kids.
That 2/7 was 3*400 = 1200
So, 2/7 x = 1200
x = 4200
3/7 of 4200 = 1800
Your mistake was in not noting that the brother only got half of the 4/7.

I did this:
Let the money be: x
Wife received: 3/7x
Brother received: x-3/7x = 4/7x
Children: 400*3= 1200
Solution:
x= 3/7x + 4/7x + 1200
Ans: 8400
Wife: 3/7 of 8400= 3600
