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