6/k+2+3=8/k+2 eching

$$\frac { 6 } { k + 2 } + 3 = \frac { 8 } { k + 2 }$$

k uchun yechish

$$k = -\frac{4}{3} = -1\frac{1}{3} \approx -1,333333333$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

k qiymati -2 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini k+2 ga ko'paytirish.

$$6+\left(k+2\right)\times 3=8$$

k+2 ga 3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$6+3k+6=8$$

12 olish uchun 6 va 6'ni qo'shing.

$$12+3k=8$$

Ikkala tarafdan 12 ni ayirish.

$$3k=8-12$$

-4 olish uchun 8 dan 12 ni ayirish.

$$3k=-4$$

Ikki tarafini 3 ga bo‘ling.

$$k=\frac{-4}{3}$$

\frac{-4}{3} kasri manfiy belgini olib tashlash bilan -\frac{4}{3} sifatida qayta yozilishi mumkin.

$$k=-\frac{4}{3}$$
