Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$400-600x-130=2-200x-15$$

270 olish uchun 400 dan 130 ni ayirish.

$$270-600x=2-200x-15$$

-13 olish uchun 2 dan 15 ni ayirish.

$$270-600x=-13-200x$$

200x ni ikki tarafga qo’shing.

$$270-600x+200x=-13$$

-400x ni olish uchun -600x va 200x ni birlashtirish.

$$270-400x=-13$$

Ikkala tarafdan 270 ni ayirish.

$$-400x=-13-270$$

-283 olish uchun -13 dan 270 ni ayirish.

$$-400x=-283$$

Ikki tarafini -400 ga bo‘ling.

$$x=\frac{-283}{-400}$$

Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-283}{-400} kasrini \frac{283}{400} ga soddalashtirish mumkin.

$$x=\frac{283}{400}$$
