12c+5=2\left(2\times 6+1\right)
Tenglamaning ikkala tarafini 12 ga, 12,6 ning eng kichik karralisiga ko‘paytiring.
12c+5=2\left(12+1\right)
12 hosil qilish uchun 2 va 6 ni ko'paytirish.
12c+5=2\times 13
13 olish uchun 12 va 1'ni qo'shing.
12c+5=26
26 hosil qilish uchun 2 va 13 ni ko'paytirish.
12c=26-5
Ikkala tarafdan 5 ni ayirish.
12c=21
21 olish uchun 26 dan 5 ni ayirish.
c=\frac{21}{12}
Ikki tarafini 12 ga bo‘ling.
c=\frac{7}{4}
\frac{21}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
