mohon nomor24 tolong dijawab yaaa

saya coba bantu ya.

pake foto aj.

x = roti donat
y = roti coklat
4x + 2y = 52,000
3x + 4y = 44,000

8x + 4y = 104,000
3x + 4y = 44,000
(dieliminasi)
5x = 60,000
x = 12,000

2x + y = 26,000 (penyederhanaan dr persamaan pertama)
2 x 12,000 + y = 26,000
24,000 + y = 26,000
y = 2,000

Anton beli 1x dan 1y, maka
x + y = 12,000 + 2,000 = 14,000

Uangnya 50,000, maka:
50,000 - 14,000 = 36,000 

Maka Anton mendapat kembalian 36,000
