He managed to get 3 of the stolen she[ him, they stole 1/2 of the remaining sheep of which he once again managed to get 2 back . He then exactly had n/2 sheep left. Determine the value of n, showing all explanations.
========
Start with n sheep
-----
Then
n - (n/4)+3 = (3/4)n+3
Then
(1/2)[(3/4)n+3]+2 = (3/8)n+(3/2)+2 = (3/8)n + 7/2
----
Solve::
Equation (3/8)n+(7/2) = n/2
-----
3n + 28 = 4n
n = 28 sheep (original number)
