Harga 5 pensil dan 2 buku adalah Rp26.000,00, sedangkan harga 3 pensil dan 4 buku Rp38.000,00. Jika harga 1 pensil dinyatakan dengan a dan harga 1 buku dinyatakan dengan b, maka sistem persamaan linear dua variabel yang tepat sesuai masalah di atas adalah
5a + 2b = 26.000 dan 4a + 3b = 38.000
5a+2b=26.000 dan 3a+4b=38.000
5a + 4b = 26.000 dan 3a + 2b = 38.000
5a + 2b = 38.000 dan 3a + 4b = 26.000

1/2 x - y = 60.000 dan 2/3 x - 1/3 y = 20.000
1/2 x + y = 60.000 dan 2/3 x + 1/3 y = 20.000
1/2 x + 1/3 y = 20.000 dan 2/3 x - y = 60.000
