Chiziqli tenglamalarni yechish bo'yicha qadamlar

1440 hosil qilish uchun 80 va 18 ni ko'paytirish.

$$1440+500\times \frac{2}{3}\times 18+120x=35000$$

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

$$1440+\frac{500\times 2}{3}\times 18+120x=35000$$

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

$$1440+\frac{1000}{3}\times 18+120x=35000$$

\frac{1000}{3}\times 18 ni yagona kasrga aylantiring.

$$1440+\frac{1000\times 18}{3}+120x=35000$$

18000 hosil qilish uchun 1000 va 18 ni ko'paytirish.

$$1440+\frac{18000}{3}+120x=35000$$

6000 ni olish uchun 18000 ni 3 ga bo‘ling.

$$1440+6000+120x=35000$$

7440 olish uchun 1440 va 6000'ni qo'shing.

$$7440+120x=35000$$

Ikkala tarafdan 7440 ni ayirish.

$$120x=35000-7440$$

27560 olish uchun 35000 dan 7440 ni ayirish.

$$120x=27560$$

Ikki tarafini 120 ga bo‘ling.

$$x=\frac{27560}{120}$$

\frac{27560}{120} ulushini 40 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{689}{3}$$
