Chiziqli tenglamalarni yechish bo'yicha qadamlar

460 olish uchun 500 dan 40 ni ayirish.

$$460-8x-20\times 2=0$$

40 hosil qilish uchun 20 va 2 ni ko'paytirish.

$$460-8x-40=0$$

420 olish uchun 460 dan 40 ni ayirish.

$$420-8x=0$$

Ikkala tarafdan 420 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-8x=-420$$

Ikki tarafini -8 ga bo‘ling.

$$x=\frac{-420}{-8}$$

\frac{-420}{-8} ulushini -4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{105}{2}$$
