3-6y=-6+18y/2 eching

$$3 - 6 y = \frac { - 6 + 18 y } { 2 }$$

y uchun yechish

$$y=\frac{2}{5}=0,4$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 2 ga ko'paytirish.

$$6-12y=-6+18y$$

Ikkala tarafdan 18y ni ayirish.

$$6-12y-18y=-6$$

-30y ni olish uchun -12y va -18y ni birlashtirish.

$$6-30y=-6$$

Ikkala tarafdan 6 ni ayirish.

$$-30y=-6-6$$

-12 olish uchun -6 dan 6 ni ayirish.

$$-30y=-12$$

Ikki tarafini -30 ga bo‘ling.

$$y=\frac{-12}{-30}$$

\frac{-12}{-30} ulushini -6 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$y=\frac{2}{5}$$
