Program LinearKelas XI
2x + 3y < 44
x + y < 18
x > 0
y > 0
• 2x + 3y = 44
y = 0 , x = 22 ➡ (22 , 0)
Titik yg diuji adalah (0 , )
• x + y = 18
x = 0 , y = 18 ➡ (0 , 18)
y = 0 , x = 18 ➡ (18 , 0)
Titik yang diuji adalah (18 , 0)
• Tipot
x + y = 18 |x 2|
2x + 2y = 36
2x + 3y = 44
_________ (–)
-y = -8
y = 8
x + 8 = 18
x = 10
Titik yang diuji (10 , 8)
f(x , y) = 4x + 5y
f(18 , 0) = 4(18) + 0 = 72
f(0 , = 0 + 5 ≈ 73,3
f(10 , 8) = 4(10) + 5(8) = 40 + 40 = 80
Nilai maks. = 80
