Yechim qadamlari

6 ga 3x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$18x-6-5\left(4x-3\right)\leq 9-2x$$

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

$$18x-6-20x+15\leq 9-2x$$

-2x ni olish uchun 18x va -20x ni birlashtirish.

$$-2x-6+15\leq 9-2x$$

9 olish uchun -6 va 15'ni qo'shing.

$$-2x+9\leq 9-2x$$

2x ni ikki tarafga qo’shing.

$$-2x+9+2x\leq 9$$

0 ni olish uchun -2x va 2x ni birlashtirish.

$$9\leq 9$$

Bu har qanday x uchun to‘g‘ri.
