Penjelasan dengan langkah-langkah:
pembilang = x
penyebut = y
x - y = 12
x = 12 + y
(x + 9)/(y + 9) = 5/8
(12 + y + 9)/(y + 9) = 5/8
(y + 21)/(y + 9) = 5/8
8(y + 21) = 5(y + 9)
8y + 168 = 5y + 45
3y = -123
y = -41
x - (-41) = 12
x = 12 - 41
x = -29
Pecahan = x/y
Pecahan = -29/(-41)
Pecahan = 29/41 (jika minus dihilangkan)
