Penjelasan dengan langkah-langkah:
3x + 2y = 10900 | x2 | 6x + 4y = 21800
2x + 5y = 16800 | x3 | 6x + 15y = 50400 __
-11y = -28600
y = 2600
3x + 2y = 10900
3x + 2(2600) = 10900
3x + 5200 = 10900
3x = 10900 - 5200
3x = 5700
x = 1900
5x + 7y
= 5(1900) + 7(2600)
= 9500 + 18200
= 27700 --> yang harus dibayarkan
