Pada suatu hari, Jack ingin bersantai di pantai tetapi dia tidak mempunya cermin mata hitam.
Harga cermin mata hitam yang dia suka bernilai RM52.
Nenek RRH mencadangkan agar Jack menjual kek. Sepotong kek RM2, 3 potong kek RM4.
Jack berjaya menjual 32 potong kek dan mendapat RM52. Lalu dia pergi membeli cermin mata hitam.
Berapakah jumlah kek yang dijual pada harga RM2 dan RM4?
Hint: guna trial and error.

2x + 4y = 52
x + 3y = 32
x = 32-3y
2(32-3y) + 4y = 52
64 - 6y + 4y = 52
y = 6, x = 14...rm2 = 14, rm4 =18 |
