Penyelesaian Program Linier Dengan Metode Simpleks

Soal :
Selesaikan linier program ini dengan metode simpleks
Maksimum Z= 2X1 + 3X2 + X3
Dengan fungsi kendala
X1 + X2 + X3≤ 9
2X1 + 3X2 ≤ 25
2X2 + 2X3  ≤ 10

Jawab:
Z= 2X1 + 3X2 + X3 + 0S1 + 0S2 + 0S3

OF
X1 + X2 + X3 + 1S1 + 0S2 + 0S3= 9
2X1 + 3X2 + 0S1 + 1S2 + 0S3 = 25
2X2 + 2X3 + 0S1 + 0S2 + 1S3 =10
