6-2(x-1)=1/5 eching

$$6 - 2 ( x - 1 ) = \frac { 1 } { 5 }$$

x uchun yechish

$$x = \frac{39}{10} = 3\frac{9}{10} = 3,9$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-2 ga x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$6-2x+2=\frac{1}{5}$$

8 olish uchun 6 va 2'ni qo'shing.

$$8-2x=\frac{1}{5}$$

Ikkala tarafdan 8 ni ayirish.

$$-2x=\frac{1}{5}-8$$

8 ni \frac{40}{5} kasrga o‘giring.

$$-2x=\frac{1}{5}-\frac{40}{5}$$

\frac{1}{5} va \frac{40}{5} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$-2x=\frac{1-40}{5}$$

-39 olish uchun 1 dan 40 ni ayirish.

$$-2x=-\frac{39}{5}$$

Ikki tarafini -2 ga bo‘ling.

$$x=\frac{-\frac{39}{5}}{-2}$$

\frac{-\frac{39}{5}}{-2} ni yagona kasrga aylantiring.

$$x=\frac{-39}{5\left(-2\right)}$$

-10 hosil qilish uchun 5 va -2 ni ko'paytirish.

$$x=\frac{-39}{-10}$$

Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-39}{-10} kasrini \frac{39}{10} ga soddalashtirish mumkin.

$$x=\frac{39}{10}$$
