Any help is appreciated!
The problem is:

Part (a) - Derive the Complementary Slackness Conditions for a primal-dual of the form:

max c^Tx
Ax = b
x \geq 0


min y^Tb
y^TA \geq c^T

Part (b) - Prove that if the primal (P) has a non-degenerate basic optimal solution, then the dual (D) has a unique optimal solition. [HINT: The matrix B in the optimal dictionary is invertible since B is a basis.]
