2\left(3x+1\right)-\left(2\times 6+1\right)=2\left(5x+8\right)
Tenglamaning ikkala tarafini 6 ga, 3,6 ning eng kichik karralisiga ko‘paytiring.
6x+2-\left(2\times 6+1\right)=2\left(5x+8\right)
2 ga 3x+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
6x+2-\left(12+1\right)=2\left(5x+8\right)
12 hosil qilish uchun 2 va 6 ni ko'paytirish.
6x+2-13=2\left(5x+8\right)
13 olish uchun 12 va 1'ni qo'shing.
6x-11=2\left(5x+8\right)
-11 olish uchun 2 dan 13 ni ayirish.
6x-11=10x+16
2 ga 5x+8 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
6x-11-10x=16
Ikkala tarafdan 10x ni ayirish.
-4x-11=16
-4x ni olish uchun 6x va -10x ni birlashtirish.
-4x=16+11
11 ni ikki tarafga qo’shing.
-4x=27
27 olish uchun 16 va 11'ni qo'shing.
x=\frac{27}{-4}
Ikki tarafini -4 ga bo‘ling.
x=-\frac{27}{4}
\frac{27}{-4} kasri manfiy belgini olib tashlash bilan -\frac{27}{4} sifatida qayta yozilishi mumkin.
