15*2+(x-15)*2+(x-15)*3=10 eching

$$15 \times 2 + ( x - 15 ) \times 2 + ( x - 15 ) \times 3 = 10$$

x uchun yechish

$$x=11$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

30 hosil qilish uchun 15 va 2 ni ko'paytirish.

$$30+\left(x-15\right)\times 2+\left(x-15\right)\times 3=10$$

x-15 ga 2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$30+2x-30+\left(x-15\right)\times 3=10$$

0 olish uchun 30 dan 30 ni ayirish.

$$2x+\left(x-15\right)\times 3=10$$

x-15 ga 3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$2x+3x-45=10$$

5x ni olish uchun 2x va 3x ni birlashtirish.

$$5x-45=10$$

45 ni ikki tarafga qo’shing.

$$5x=10+45$$

55 olish uchun 10 va 45'ni qo'shing.

$$5x=55$$

Ikki tarafini 5 ga bo‘ling.

$$x=\frac{55}{5}$$

11 ni olish uchun 55 ni 5 ga bo‘ling.

$$x=11$$
