x uchun yechish

$$x = \frac{255}{7} = 36\frac{3}{7} \approx 36,428571429$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

540 hosil qilish uchun 36 va 15 ni ko'paytirish.

$$3x+90+540+45\left(25-x\right)=225$$

630 olish uchun 90 va 540'ni qo'shing.

$$3x+630+45\left(25-x\right)=225$$

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

$$3x+630+1125-45x=225$$

1755 olish uchun 630 va 1125'ni qo'shing.

$$3x+1755-45x=225$$

-42x ni olish uchun 3x va -45x ni birlashtirish.

$$-42x+1755=225$$

Ikkala tarafdan 1755 ni ayirish.

$$-42x=225-1755$$

-1530 olish uchun 225 dan 1755 ni ayirish.

$$-42x=-1530$$

Ikki tarafini -42 ga bo‘ling.

$$x=\frac{-1530}{-42}$$

\frac{-1530}{-42} ulushini -6 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{255}{7}$$
