2 Kg apel = 6 Kg jeruk, berarti 2X = 6Y
2 Kg apel + 4 Kg jeruk = 195 000, dpt ditulis 2X + 4Y = 195 000
Karena 2X = 6Y, maka 2X + 4Y = 195 000
(6Y) + 4Y = 195 000
10Y = 195 000
Y = 19 500, harga jeruk 19 500/Kg.
Karena 2X = 6Y, maka X = 3Y -> 3 x 19 500 = 58 500/Kg apel.
Ibu Eva membayar:
5 Kg apel + 3 Kg jeruk atau 5X + 3Y.
(5 x 58 500) + (3 x 19 500)
292 500 + 58 500 = 351 000.
