7(3-4x)+12>5(4-3x) eching

$$7 ( 3 - 4 x ) + 12 > 5 ( 4 - 3 x )$$

x uchun yechish

$$x<1$$

Yechim qadamlari

7 ga 3-4x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$21-28x+12>5\left(4-3x\right)$$

33 olish uchun 21 va 12'ni qo'shing.

$$33-28x>5\left(4-3x\right)$$

5 ga 4-3x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$33-28x>20-15x$$

15x ni ikki tarafga qo’shing.

$$33-28x+15x>20$$

-13x ni olish uchun -28x va 15x ni birlashtirish.

$$33-13x>20$$

Ikkala tarafdan 33 ni ayirish.

$$-13x>20-33$$

-13 olish uchun 20 dan 33 ni ayirish.

$$-13x>-13$$

Ikki tarafini -13 ga bo‘ling. -13 manfiy boʻlgani uchun tengsizlikning yo‘nalishi o‘zgaradi.

$$x<\frac{-13}{-13}$$

1 ni olish uchun -13 ni -13 ga bo‘ling.

$$x<1$$
