10k+2\left(1\times 5+3\right)=2\times 10+7
Tenglamaning ikkala tarafini 10 ga, 5,10 ning eng kichik karralisiga ko‘paytiring.
10k+2\left(5+3\right)=2\times 10+7
5 hosil qilish uchun 1 va 5 ni ko'paytirish.
10k+2\times 8=2\times 10+7
8 olish uchun 5 va 3'ni qo'shing.
10k+16=2\times 10+7
16 hosil qilish uchun 2 va 8 ni ko'paytirish.
10k+16=20+7
20 hosil qilish uchun 2 va 10 ni ko'paytirish.
10k+16=27
27 olish uchun 20 va 7'ni qo'shing.
10k=27-16
Ikkala tarafdan 16 ni ayirish.
10k=11
11 olish uchun 27 dan 16 ni ayirish.
k=\frac{11}{10}
Ikki tarafini 10 ga bo‘ling.
