bantu kerjain dong urgent

maaf kalo salah ......

jawab

2x + 3y  = 6
x = 0, y = 2→ (0,2)
y = 0 , x = 3 → (3,0)

5x + 10y = 20
x = 0, y = 2 → (0,2)
y = 0 , x = 4 → (4,0)

titik potong
2x+ 3y = 6 ...kali5
5x + 10y = 20..kali 2

10x + 15y = 30
10x + 20y = 40 ...(-)
- 5y = -10
y = 2 , x = 0

nilai minimum z = 3x + 2y pada titik pojok HP
(0,2) → Z= 4
(3,0) → Z = 9
(0,0) → Z = 0
nilai min = 0
nilai mak = 9
