X + 2y ≤ 10
x + y ≤ 7
x ≥ 0 ; y≥ 0.

Perpotongan x + 2y = 10 dan x + y = 7 ( atau x = 7 - y ) pada :
x + 2y = 10 ==> (7 - y) + 2y = 10
                          7 + y = 10
                               y =  10 - 7 = 3

x + (2 × 3) = 10
x = 10 - 6 = 4

Jadi nilai maksimum 2x + 3y = (2 × 4) + (3 × 3) = 8 + 9 = 17
