Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$14+25x-75+38\left(x-15-3\right)=82$$

-61 olish uchun 14 dan 75 ni ayirish.

$$-61+25x+38\left(x-15-3\right)=82$$

-18 olish uchun -15 dan 3 ni ayirish.

$$-61+25x+38\left(x-18\right)=82$$

38 ga x-18 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$-61+25x+38x-684=82$$

63x ni olish uchun 25x va 38x ni birlashtirish.

$$-61+63x-684=82$$

-745 olish uchun -61 dan 684 ni ayirish.

$$-745+63x=82$$

745 ni ikki tarafga qo’shing.

$$63x=82+745$$

827 olish uchun 82 va 745'ni qo'shing.

$$63x=827$$

Ikki tarafini 63 ga bo‘ling.

$$x=\frac{827}{63}$$
