9(2x-1)=3(x+2)+3x eching

$$9(2x-1)=3(x+2)+3x$$

x uchun yechish

$$x = \frac{5}{4} = 1\frac{1}{4} = 1,25$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

9 ga 2x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$18x-9=3\left(x+2\right)+3x$$

3 ga x+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$18x-9=3x+6+3x$$

6x ni olish uchun 3x va 3x ni birlashtirish.

$$18x-9=6x+6$$

Ikkala tarafdan 6x ni ayirish.

$$18x-9-6x=6$$

12x ni olish uchun 18x va -6x ni birlashtirish.

$$12x-9=6$$

9 ni ikki tarafga qo’shing.

$$12x=6+9$$

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

$$12x=15$$

Ikki tarafini 12 ga bo‘ling.

$$x=\frac{15}{12}$$

\frac{15}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{5}{4}$$
