3(y+2)-2(2y-3)=12 eching

$$3 ( y + 2 ) - 2 ( 2 y - 3 ) = 12$$

y uchun yechish

$$y=0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

3 ga y+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$3y+6-2\left(2y-3\right)=12$$

-2 ga 2y-3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$3y+6-4y+6=12$$

-y ni olish uchun 3y va -4y ni birlashtirish.

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

12 olish uchun 6 va 6'ni qo'shing.

$$-y+12=12$$

Ikkala tarafdan 12 ni ayirish.

$$-y=12-12$$

0 olish uchun 12 dan 12 ni ayirish.

$$-y=0$$

Ikki son koʻpaytmasi 0 ga teng, agar kamida bittasi 0 bo‘lsa. -1 0 ga teng bo‘lmasa, y 0 ga teng bo‘lishi kerak.

$$y=0$$
