Sir please complete duality

in last question x2 is unrestricted so 2nd constraint of dual problem would be '=' sign not '

Its really great that you do sucha. Hard work and also provide it at free of cost kudos to you thanks helped me a alot 😊

[@mdsalmankhan9089]

There's one error in the last problem that you've taken. Since the 2nd variable x_2 was unrestricted in the primal, so the 2nd constraint of the dual should have an equal sign.

[@hamzaparis3640]

Yes,sir I solved last problem in both case means when in primal form and after I solved it in dual form by big M-Method,both give same results (Max:z=20/3)only when w1,w2',w2" is used in problem not only sayings"w2" is unrestricted.but when we say that "w2"is unrestricted it gave the result(Max:z=9) in dual form which is wrong.because both results must be same...

Hlo sir you are doing a great job for students who can't afford coaching class you are best teacher I have found on KZbin . Whenever I am unable you understand any topic I search for your video you are my role model I want to become a teacher like you so that I can also help others I was little scared when I took admission in msc but I now I feel so interesting to study all the topics.
