6n+12=7\left(4n+3\right)+7
3 ga 2n+4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
6n+12=28n+21+7
7 ga 4n+3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
6n+12=28n+28
28 olish uchun 21 va 7'ni qo'shing.
6n+12-28n=28
Ikkala tarafdan 28n ni ayirish.
-22n+12=28
-22n ni olish uchun 6n va -28n ni birlashtirish.
-22n=28-12
Ikkala tarafdan 12 ni ayirish.
-22n=16
16 olish uchun 28 dan 12 ni ayirish.
n=\frac{16}{-22}
Ikki tarafini -22 ga bo‘ling.
n=-\frac{8}{11}
\frac{16}{-22} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
