6x-18-2\left(2x+8\right)=12x-3
Tenglamaning ikkala tarafini 3 ga ko'paytirish.
6x-18-4x-16=12x-3
-2 ga 2x+8 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2x-18-16=12x-3
2x ni olish uchun 6x va -4x ni birlashtirish.
2x-34=12x-3
-34 olish uchun -18 dan 16 ni ayirish.
2x-34-12x=-3
Ikkala tarafdan 12x ni ayirish.
-10x-34=-3
-10x ni olish uchun 2x va -12x ni birlashtirish.
-10x=-3+34
34 ni ikki tarafga qo’shing.
-10x=31
31 olish uchun -3 va 34'ni qo'shing.
x=\frac{31}{-10}
Ikki tarafini -10 ga bo‘ling.
x=-\frac{31}{10}
\frac{31}{-10} kasri manfiy belgini olib tashlash bilan -\frac{31}{10} sifatida qayta yozilishi mumkin.
