Question $2$ For primal linear program $=$ min $,$ s u b j e c t t o $>=$ P$=$min x c T x$,$subjecttoAx$>=$b$,$ with $=[1,1],=[1,2],=[1121],=[1,1]$ c$=[1,1]$ T $,$x$=[$x $1,$x $2]$ T $,$A$=[1211],$b$=[1,1]$ T $.$ Suppose the variable in dual program is $=[1,2]$ u$=[$u $1,$u $2]$ T $.$ From the constrains, you can solve for $1$ u $1$ and $2$ u $2.$ Suppose strong duality holds, what is the optimal value of the primal linear program P$?$
