$$x = \frac{16}{15} = 1\frac{1}{15} \approx 1,066666667$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikki tarafini 5 ga bo‘ling.

$$12x-15=-\frac{11}{5}$$

15 ni ikki tarafga qo’shing.

$$12x=-\frac{11}{5}+15$$

15 ni \frac{75}{5} kasrga o‘giring.

$$12x=-\frac{11}{5}+\frac{75}{5}$$

-\frac{11}{5} va \frac{75}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$12x=\frac{-11+75}{5}$$

64 olish uchun -11 va 75'ni qo'shing.

$$12x=\frac{64}{5}$$

Ikki tarafini 12 ga bo‘ling.

$$x=\frac{\frac{64}{5}}{12}$$

\frac{\frac{64}{5}}{12} ni yagona kasrga aylantiring.

$$x=\frac{64}{5\times 12}$$

60 hosil qilish uchun 5 va 12 ni ko'paytirish.

$$x=\frac{64}{60}$$

\frac{64}{60} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{16}{15}$$
