9f=1/2left(12f-2right) eching

$$9f = \frac{ 1 }{ 2 } \left( 12f-2 \right)$$

f uchun yechish

$$f=-\frac{1}{3}\approx -0,333333333$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{1}{2} ga 12f-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$9f=\frac{1}{2}\times 12f+\frac{1}{2}\left(-2\right)$$

\frac{12}{2} hosil qilish uchun \frac{1}{2} va 12 ni ko'paytirish.

$$9f=\frac{12}{2}f+\frac{1}{2}\left(-2\right)$$

6 ni olish uchun 12 ni 2 ga bo‘ling.

$$9f=6f+\frac{1}{2}\left(-2\right)$$

\frac{-2}{2} hosil qilish uchun \frac{1}{2} va -2 ni ko'paytirish.

$$9f=6f+\frac{-2}{2}$$

-1 ni olish uchun -2 ni 2 ga bo‘ling.

$$9f=6f-1$$

Ikkala tarafdan 6f ni ayirish.

$$9f-6f=-1$$

3f ni olish uchun 9f va -6f ni birlashtirish.

$$3f=-1$$

Ikki tarafini 3 ga bo‘ling.

$$f=\frac{-1}{3}$$

\frac{-1}{3} kasri manfiy belgini olib tashlash bilan -\frac{1}{3} sifatida qayta yozilishi mumkin.

$$f=-\frac{1}{3}$$
