-3(x+2)+39leq5(3-x) eching

$$- 3 ( x + 2 ) + 39 \leq 5 ( 3 - x )$$

x uchun yechish

$$x\leq -9$$

Yechim qadamlari

-3 ga x+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$-3x-6+39\leq 5\left(3-x\right)$$

33 olish uchun -6 va 39'ni qo'shing.

$$-3x+33\leq 5\left(3-x\right)$$

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

$$-3x+33\leq 15-5x$$

5x ni ikki tarafga qo’shing.

$$-3x+33+5x\leq 15$$

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

$$2x+33\leq 15$$

Ikkala tarafdan 33 ni ayirish.

$$2x\leq 15-33$$

-18 olish uchun 15 dan 33 ni ayirish.

$$2x\leq -18$$

Ikki tarafini 2 ga bo‘ling. 2 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.

$$x\leq \frac{-18}{2}$$

-9 ni olish uchun -18 ni 2 ga bo‘ling.

$$x\leq -9$$
