  • Bab Program Linear
    Matematika SMA Kelas XI

    daerah yang diarsir, 4 sampai 3
    x + y = 3
    4x + 2y = 8 → 2x + y = 4

    2x + y = 4
    x + y = 3
    ------------------ -
    x = 1

    x + y = 3
    y = 3 - 1
    y = 2 → (1,2)

    R(x,y) = 3x + 2y → nilai minimum ?

    (0,4)
    R(0,4) = 3 . 0 + 2 . 4 = 8

    (0,3)
    R(0,3) = 3 . 0 + 2 . 3 = 6

    (1,2)
    R(1,2) = 3 . 1 + 2 . 2 = 7

    maka, nilai minimum = 6
