f(x,y) = 2y-3x+6
garis 1 : x≤4
garis 2 : y≤3
garis 3 : x+y≥4
titik potong :
g1 : x+y = 4
g2 : x = 4
4 + y = 4
y = 0
titik potong 1 : (4,0)
x+y = 4
y = 3
x+3 = 4
x = 1
titik potong 2 : (1,3)
titik potong 3 ada di pertemuan garis y = 3 dan x = 4, yaitu (4,3)
f(x,y) = 2y-3x+6 <= x = 4, y = 0
f(4,0) = 2.0-3.4+6 = -12+6 = -6
f(1,3) = 2.3-3.1+6 = 9
f(4,3) = 2.3-3.4+6 = 0
nilai maksimum : f(1,3) = 9
