8\left(2x-4\right)=5\left(4x+1\right)
Tenglamaning ikkala tarafini 40 ga, 5,8 ning eng kichik karralisiga ko‘paytiring.
16x-32=5\left(4x+1\right)
8 ga 2x-4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
16x-32=20x+5
5 ga 4x+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
16x-32-20x=5
Ikkala tarafdan 20x ni ayirish.
-4x-32=5
-4x ni olish uchun 16x va -20x ni birlashtirish.
-4x=5+32
32 ni ikki tarafga qo’shing.
-4x=37
37 olish uchun 5 va 32'ni qo'shing.
x=\frac{37}{-4}
Ikki tarafini -4 ga bo‘ling.
x=-\frac{37}{4}
\frac{37}{-4} kasri manfiy belgini olib tashlash bilan -\frac{37}{4} sifatida qayta yozilishi mumkin.
