4\times 3x=5\left(x-2\right)
Tenglamaning ikkala tarafini 20 ga, 5,4 ning eng kichik karralisiga ko‘paytiring.
12x=5\left(x-2\right)
12 hosil qilish uchun 4 va 3 ni ko'paytirish.
12x=5x-10
5 ga x-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
12x-5x=-10
Ikkala tarafdan 5x ni ayirish.
7x=-10
7x ni olish uchun 12x va -5x ni birlashtirish.
x=\frac{-10}{7}
Ikki tarafini 7 ga bo‘ling.
x=-\frac{10}{7}
\frac{-10}{7} kasri manfiy belgini olib tashlash bilan -\frac{10}{7} sifatida qayta yozilishi mumkin.
