Chiziqli tenglamalarni yechish bo'yicha qadamlar

2 ga 400-600x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$800-1200x-65\times 2=2-200x-15$$

130 hosil qilish uchun 65 va 2 ni ko'paytirish.

$$800-1200x-130=2-200x-15$$

670 olish uchun 800 dan 130 ni ayirish.

$$670-1200x=2-200x-15$$

-13 olish uchun 2 dan 15 ni ayirish.

$$670-1200x=-13-200x$$

200x ni ikki tarafga qo’shing.

$$670-1200x+200x=-13$$

-1000x ni olish uchun -1200x va 200x ni birlashtirish.

$$670-1000x=-13$$

Ikkala tarafdan 670 ni ayirish.

$$-1000x=-13-670$$

-683 olish uchun -13 dan 670 ni ayirish.

$$-1000x=-683$$

Ikki tarafini -1000 ga bo‘ling.

$$x=\frac{-683}{-1000}$$

Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-683}{-1000} kasrini \frac{683}{1000} ga soddalashtirish mumkin.

$$x=\frac{683}{1000}$$
