5\left(3t-2\right)=4\left(5t+1\right)
Tenglamaning ikkala tarafini 20 ga, 4,5 ning eng kichik karralisiga ko‘paytiring.
15t-10=4\left(5t+1\right)
5 ga 3t-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
15t-10=20t+4
4 ga 5t+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
15t-10-20t=4
Ikkala tarafdan 20t ni ayirish.
-5t-10=4
-5t ni olish uchun 15t va -20t ni birlashtirish.
-5t=4+10
10 ni ikki tarafga qo’shing.
-5t=14
14 olish uchun 4 va 10'ni qo'shing.
t=\frac{14}{-5}
Ikki tarafini -5 ga bo‘ling.
t=-\frac{14}{5}
\frac{14}{-5} kasri manfiy belgini olib tashlash bilan -\frac{14}{5} sifatida qayta yozilishi mumkin.
