Question

For the given simplex​ tableau, (a) list the basic and the nonbasic​ variables, (b) find the basic feasible solution determined by setting the nonbasic variables equal to​ 0, and​ (c) decide whether this is a maximum solution.

	x 1x1	x 2x2	x 3x3	s 1s1	s 2s2	zz
	77	00	22	negative 1−1	11	00	2525
	22	11	00	negative 3−3	00	00	1818
	negative 8−8	00	negative 2−2	negative 1−1	00	11	1111

​(a) What are the basic​ variables?

What are the nonbasic​ variables?

​(b) Find the basic feasible solution by setting the nonbasic variables equal to 0.

x 1x1equals=nothing​,

x 2x2equals=nothing​,

x 3x3equals=nothing​,

s 1s1equals=nothing​,

s 2s2equals=nothing​,

zequals=nothing

c) Is this solution a​ maximum?
