3(x-1)geq1 eching

$$3 ( x - 1 ) \geq 1$$

x uchun yechish

$$x\geq \frac{4}{3}$$

Yechim qadamlari

Ikki tarafini 3 ga bo‘ling. 3 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.

$$x-1\geq \frac{1}{3}$$

1 ni ikki tarafga qo’shing.

$$x\geq \frac{1}{3}+1$$

1 ni \frac{3}{3} kasrga o‘giring.

$$x\geq \frac{1}{3}+\frac{3}{3}$$

\frac{1}{3} va \frac{3}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$x\geq \frac{1+3}{3}$$

4 olish uchun 1 va 3'ni qo'shing.

$$x\geq \frac{4}{3}$$
