3(6r-5)+2r=3(r-5)-5r eching

$$3 ( 6 r - 5 ) + 2 r = 3 ( r - 5 ) - 5 r$$

r uchun yechish

$$r=0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

3 ga 6r-5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$18r-15+2r=3\left(r-5\right)-5r$$

20r ni olish uchun 18r va 2r ni birlashtirish.

$$20r-15=3\left(r-5\right)-5r$$

3 ga r-5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$20r-15=3r-15-5r$$

-2r ni olish uchun 3r va -5r ni birlashtirish.

$$20r-15=-2r-15$$

2r ni ikki tarafga qo’shing.

$$20r-15+2r=-15$$

22r ni olish uchun 20r va 2r ni birlashtirish.

$$22r-15=-15$$

15 ni ikki tarafga qo’shing.

$$22r=-15+15$$

0 olish uchun -15 va 15'ni qo'shing.

$$22r=0$$

Ikki son koʻpaytmasi 0 ga teng, agar kamida bittasi 0 bo‘lsa. 22 0 ga teng bo‘lmasa, r 0 ga teng bo‘lishi kerak.

$$r=0$$
