Chiziqli tenglamalarni yechish bo'yicha qadamlar

800 hosil qilish uchun 80 va 10 ni ko'paytirish.

$$800+120x+500\times \frac{2}{3}\times 12-35000=0$$

500\times \frac{2}{3} ni yagona kasrga aylantiring.

$$800+120x+\frac{500\times 2}{3}\times 12-35000=0$$

1000 hosil qilish uchun 500 va 2 ni ko'paytirish.

$$800+120x+\frac{1000}{3}\times 12-35000=0$$

\frac{1000}{3}\times 12 ni yagona kasrga aylantiring.

$$800+120x+\frac{1000\times 12}{3}-35000=0$$

12000 hosil qilish uchun 1000 va 12 ni ko'paytirish.

$$800+120x+\frac{12000}{3}-35000=0$$

4000 ni olish uchun 12000 ni 3 ga bo‘ling.

$$800+120x+4000-35000=0$$

4800 olish uchun 800 va 4000'ni qo'shing.

$$4800+120x-35000=0$$

-30200 olish uchun 4800 dan 35000 ni ayirish.

$$-30200+120x=0$$

30200 ni ikki tarafga qo’shing. Har qanday songa nolni qo‘shsangiz, o‘zi chiqadi.

$$120x=30200$$

Ikki tarafini 120 ga bo‘ling.

$$x=\frac{30200}{120}$$

\frac{30200}{120} ulushini 40 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{755}{3}$$
