-2a-1geq-1/2a-3 eching

$$- 2 a - 1 \geq - \frac { 1 } { 2 } a - 3$$

a uchun yechish

$$a\leq \frac{4}{3}$$

Yechim qadamlari

\frac{1}{2}a ni ikki tarafga qo’shing.

$$-2a-1+\frac{1}{2}a\geq -3$$

-\frac{3}{2}a ni olish uchun -2a va \frac{1}{2}a ni birlashtirish.

$$-\frac{3}{2}a-1\geq -3$$

1 ni ikki tarafga qo’shing.

$$-\frac{3}{2}a\geq -3+1$$

-2 olish uchun -3 va 1'ni qo'shing.

$$-\frac{3}{2}a\geq -2$$

Ikki tarafini -\frac{2}{3} va teskari kasri -\frac{3}{2} ga ko‘paytiring. -\frac{3}{2} manfiy boʻlgani uchun tengsizlikning yo‘nalishi o‘zgaradi.

$$a\leq -2\left(-\frac{2}{3}\right)$$

-2\left(-\frac{2}{3}\right) ni yagona kasrga aylantiring.

$$a\leq \frac{-2\left(-2\right)}{3}$$

4 hosil qilish uchun -2 va -2 ni ko'paytirish.

$$a\leq \frac{4}{3}$$
