7(-3m+5)=3(10-6m) eching

$$7 ( - 3 m + 5 ) = 3 ( 10 - 6 m )$$

m uchun yechish

$$m = \frac{5}{3} = 1\frac{2}{3} \approx 1,666666667$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

7 ga -3m+5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$-21m+35=3\left(10-6m\right)$$

3 ga 10-6m ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$-21m+35=30-18m$$

18m ni ikki tarafga qo’shing.

$$-21m+35+18m=30$$

-3m ni olish uchun -21m va 18m ni birlashtirish.

$$-3m+35=30$$

Ikkala tarafdan 35 ni ayirish.

$$-3m=30-35$$

-5 olish uchun 30 dan 35 ni ayirish.

$$-3m=-5$$

Ikki tarafini -3 ga bo‘ling.

$$m=\frac{-5}{-3}$$

Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-5}{-3} kasrini \frac{5}{3} ga soddalashtirish mumkin.

$$m=\frac{5}{3}$$
