4(3x-5)+7geq8x+3 eching

$$4 ( 3 x - 5 ) + 7 \geq 8 x + 3$$

x uchun yechish

$$x\geq 4$$

Yechim qadamlari

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

$$12x-20+7\geq 8x+3$$

-13 olish uchun -20 va 7'ni qo'shing.

$$12x-13\geq 8x+3$$

Ikkala tarafdan 8x ni ayirish.

$$12x-13-8x\geq 3$$

4x ni olish uchun 12x va -8x ni birlashtirish.

$$4x-13\geq 3$$

13 ni ikki tarafga qo’shing.

$$4x\geq 3+13$$

16 olish uchun 3 va 13'ni qo'shing.

$$4x\geq 16$$

Ikki tarafini 4 ga bo‘ling. 4 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.

$$x\geq \frac{16}{4}$$

4 ni olish uchun 16 ni 4 ga bo‘ling.

$$x\geq 4$$
