5(c+3)+4(c-2)=2(c+2) eching

$$5 ( c + 3 ) + 4 ( c - 2 ) = 2 ( c + 2 )$$

c uchun yechish

$$c=-\frac{3}{7}\approx -0,428571429$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

5 ga c+3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$5c+15+4\left(c-2\right)=2\left(c+2\right)$$

4 ga c-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$5c+15+4c-8=2\left(c+2\right)$$

9c ni olish uchun 5c va 4c ni birlashtirish.

$$9c+15-8=2\left(c+2\right)$$

7 olish uchun 15 dan 8 ni ayirish.

$$9c+7=2\left(c+2\right)$$

2 ga c+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$9c+7=2c+4$$

Ikkala tarafdan 2c ni ayirish.

$$9c+7-2c=4$$

7c ni olish uchun 9c va -2c ni birlashtirish.

$$7c+7=4$$

Ikkala tarafdan 7 ni ayirish.

$$7c=4-7$$

-3 olish uchun 4 dan 7 ni ayirish.

$$7c=-3$$

Ikki tarafini 7 ga bo‘ling.

$$c=\frac{-3}{7}$$

\frac{-3}{7} kasri manfiy belgini olib tashlash bilan -\frac{3}{7} sifatida qayta yozilishi mumkin.

$$c=-\frac{3}{7}$$
