$$2 \pi x + 4 \pi \geq - 6 \pi$$

x uchun yechish

$$x\geq -5$$

Yechim qadamlari

Ikkala tarafdan 4\pi ni ayirish.

$$2\pi x\geq -6\pi -4\pi$$

-10\pi ni olish uchun -6\pi va -4\pi ni birlashtirish.

$$2\pi x\geq -10\pi$$

\pi ni ikki tarafidan bekor qilish. \pi musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.

$$2x\geq -10$$

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

$$x\geq \frac{-10}{2}$$

-5 ni olish uchun -10 ni 2 ga bo‘ling.

$$x\geq -5$$
