15(6+t)=20t eching

$$15 ( 6 + t ) = 20 t$$

t uchun yechish

$$t=18$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

15 ga 6+t ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$90+15t=20t$$

Ikkala tarafdan 20t ni ayirish.

$$90+15t-20t=0$$

-5t ni olish uchun 15t va -20t ni birlashtirish.

$$90-5t=0$$

Ikkala tarafdan 90 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-5t=-90$$

Ikki tarafini -5 ga bo‘ling.

$$t=\frac{-90}{-5}$$

18 ni olish uchun -90 ni -5 ga bo‘ling.

$$t=18$$
