Yechim qadamlari

Tenglamaning ikkala tarafini 6 ga, 2,3 ning eng kichik karralisiga ko‘paytiring. 6 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.

$$3\left(13+1\right)\geq 54\times \frac{4}{3}-30$$

14 olish uchun 13 va 1'ni qo'shing.

$$3\times 14\geq 54\times \frac{4}{3}-30$$

42 hosil qilish uchun 3 va 14 ni ko'paytirish.

$$42\geq 54\times \frac{4}{3}-30$$

54\times \frac{4}{3} ni yagona kasrga aylantiring.

$$42\geq \frac{54\times 4}{3}-30$$

216 hosil qilish uchun 54 va 4 ni ko'paytirish.

$$42\geq \frac{216}{3}-30$$

72 ni olish uchun 216 ni 3 ga bo‘ling.

$$42\geq 72-30$$

42 olish uchun 72 dan 30 ni ayirish.

$$42\geq 42$$

42 va 42 ni taqqoslang.
