Misalkan : x = baju
y = kaos
Penjelasan dengan langkah-langkah:
2x + y = 170.000 | x3 | 6x + 3y = 510.000
x + 3y = 185.000 | x1 | x + 3y = 185.000
------------------------- -
5x = 325.000
x = 65.000
2x + y = 170.000
2(65.000) + y = 170.000
130.000 + y = 170.000
y = 170.000 - 130.000
y = 40.000
Harga untuk tiga baju dan dua kaos
3x + 2y = 3(65.000) + 2(40.000)
= 195.000 + 80.000
= Rp. 275.000,00
