harga 3 kg salak dan 2 kg kedondong Rp19,500,00. sedangkan harga 2 kg salak dan 3 kg kedondong Rp20.000,00. harga 2 kg salak adalah

Dik:
3 Salak + 2 Kedondong = 19,500
2 Salak + 3 Kedondong = 20,000

3S + 2K = 19,500 |×2| = 6S + 4K = 39,000
2S + 3K = 20,000 |×3| = 6S + 9K = 60,000

•) 6S + 4K = 39,000
6S + 9K = 60,000
______________(-)
-5K = -21,000
K = 4,200

•) 2S + 3K = 20,000
2S + 3(4,200)= 20,000
2S + 12,600 = 20,000
2S = 20,000 - 12,600
2S = 7,400
S = 3,700

Jadi, harag 2 Kg salak adalah
2 Kg Salak = 2 x 3700
