13-2(a-1)=6+a eching

$$13 - 2 ( a - 1 ) = 6 + a$$

a uchun yechish

$$a=3$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-2 ga a-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$13-2a+2=6+a$$

15 olish uchun 13 va 2'ni qo'shing.

$$15-2a=6+a$$

Ikkala tarafdan a ni ayirish.

$$15-2a-a=6$$

-3a ni olish uchun -2a va -a ni birlashtirish.

$$15-3a=6$$

Ikkala tarafdan 15 ni ayirish.

$$-3a=6-15$$

-9 olish uchun 6 dan 15 ni ayirish.

$$-3a=-9$$

Ikki tarafini -3 ga bo‘ling.

$$a=\frac{-9}{-3}$$

3 ni olish uchun -9 ni -3 ga bo‘ling.

$$a=3$$
