5-17tgeq-20-11t+7 eching

$$5 - 17 t \geq - 20 - 11 t + 7$$

t uchun yechish

$$t\leq 3$$

Yechim qadamlari

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

$$5-17t\geq -13-11t$$

11t ni ikki tarafga qo’shing.

$$5-17t+11t\geq -13$$

-6t ni olish uchun -17t va 11t ni birlashtirish.

$$5-6t\geq -13$$

Ikkala tarafdan 5 ni ayirish.

$$-6t\geq -13-5$$

-18 olish uchun -13 dan 5 ni ayirish.

$$-6t\geq -18$$

Ikki tarafini -6 ga bo‘ling. -6 <0 bo‘lganda, tengsizlikning yo‘nalishi o‘zgargan bo‘ladi.

$$t\leq \frac{-18}{-6}$$

3 ni olish uchun -18 ni -6 ga bo‘ling.

$$t\leq 3$$
