x-9/7=-19/2 eching

$$x- \frac{ 9 }{ 7 } =- \frac{ 19 }{ 2 }$$

x uchun yechish

$$x = -\frac{115}{14} = -8\frac{3}{14} \approx -8,214285714$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{9}{7} ni ikki tarafga qo’shing.

$$x=-\frac{19}{2}+\frac{9}{7}$$

2 va 7 ning eng kichik umumiy karralisi 14 ga teng. -\frac{19}{2} va \frac{9}{7} ni 14 maxraj bilan kasrlarga aylantirib oling.

$$x=-\frac{133}{14}+\frac{18}{14}$$

-\frac{133}{14} va \frac{18}{14} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$x=\frac{-133+18}{14}$$

-115 olish uchun -133 va 18'ni qo'shing.

$$x=-\frac{115}{14}$$
