Example of Simplex Method, continued.
Want to keep doing this, need to get back into state where x,b,c on l.h.s. of equations.
a = 5-2x-3y-z => x= 5/2 -3/2 y -1/2 z - 1/2 a (*)
Substituting (*) into other equations:
b = 11-4x-y-2z >=0 => b = 1 + 5y + 2a
c = 8-3x-4y-2z >=0 => c = 1/2 + 1/2 y -1/2 z + 3/2 a
F = 5x+4y + 3z => F= 25/2 - 7/2 y + 1/2 z - 5/2 a
In order to increase F again, should increase
