6x-2\times 7\left(x-2\right)=72-3\left(2x-5\right)
Tenglamaning ikkala tarafini 18 ga, 3,9,6 ning eng kichik karralisiga ko‘paytiring.
6x-14\left(x-2\right)=72-3\left(2x-5\right)
-14 hosil qilish uchun -2 va 7 ni ko'paytirish.
6x-14x+28=72-3\left(2x-5\right)
-14 ga x-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-8x+28=72-3\left(2x-5\right)
-8x ni olish uchun 6x va -14x ni birlashtirish.
-8x+28=72-6x+15
-3 ga 2x-5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-8x+28=87-6x
87 olish uchun 72 va 15'ni qo'shing.
-8x+28+6x=87
6x ni ikki tarafga qo’shing.
-2x+28=87
-2x ni olish uchun -8x va 6x ni birlashtirish.
-2x=87-28
Ikkala tarafdan 28 ni ayirish.
-2x=59
59 olish uchun 87 dan 28 ni ayirish.
x=\frac{59}{-2}
Ikki tarafini -2 ga bo‘ling.
x=-\frac{59}{2}
\frac{59}{-2} kasri manfiy belgini olib tashlash bilan -\frac{59}{2} sifatida qayta yozilishi mumkin.
