The son received $ 3000.
Step-by-step explanation:
Given,
The wife got twice as much as daughter
The son got $1000 more the daughter
The total amount of distribution is $ 9000
To find the amount received by the son
Let us take, the wife received $x
So, the daughter received = $
And the son received = $
+1000
According to the problem
x+
+
+1000 = 9000
or,
2x = 8000
or, x = 4000
Hence, the daughter received = $ 2000
The son received = $ 3000
