You will have to add slack and surplus variables. b). An implementation of the simplex method has found an optimal solution to this LP to be given by x' = (x'1,x*2,x'3,x'4,x'5,x'6) = (0,5,0,0,4,0). By determining the appropriate values for the slack and surplus variables, convert this to a solution to the LP you wrote in part (a). Determine which are the basic variables and write out the corresponding basis matrix
