2x+9=-17/7 eching

$$2x+9= \frac{ -17 }{ 7 }$$

x uchun yechish

$$x = -\frac{40}{7} = -5\frac{5}{7} \approx -5,714285714$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{-17}{7} kasri manfiy belgini olib tashlash bilan -\frac{17}{7} sifatida qayta yozilishi mumkin.

$$2x+9=-\frac{17}{7}$$

Ikkala tarafdan 9 ni ayirish.

$$2x=-\frac{17}{7}-9$$

9 ni \frac{63}{7} kasrga o‘giring.

$$2x=-\frac{17}{7}-\frac{63}{7}$$

-\frac{17}{7} va \frac{63}{7} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$2x=\frac{-17-63}{7}$$

-80 olish uchun -17 dan 63 ni ayirish.

$$2x=-\frac{80}{7}$$

Ikki tarafini 2 ga bo‘ling.

$$x=\frac{-\frac{80}{7}}{2}$$

\frac{-\frac{80}{7}}{2} ni yagona kasrga aylantiring.

$$x=\frac{-80}{7\times 2}$$

14 hosil qilish uchun 7 va 2 ni ko'paytirish.

$$x=\frac{-80}{14}$$

\frac{-80}{14} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=-\frac{40}{7}$$
