72*x+15*80=(x+15)*75 eching

$$72 \cdot x + 15 \cdot 80 = ( x + 15 ) \cdot 75$$

x uchun yechish

$$x=25$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

1200 hosil qilish uchun 15 va 80 ni ko'paytirish.

$$72x+1200=\left(x+15\right)\times 75$$

x+15 ga 75 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$72x+1200=75x+1125$$

Ikkala tarafdan 75x ni ayirish.

$$72x+1200-75x=1125$$

-3x ni olish uchun 72x va -75x ni birlashtirish.

$$-3x+1200=1125$$

Ikkala tarafdan 1200 ni ayirish.

$$-3x=1125-1200$$

-75 olish uchun 1125 dan 1200 ni ayirish.

$$-3x=-75$$

Ikki tarafini -3 ga bo‘ling.

$$x=\frac{-75}{-3}$$

25 ni olish uchun -75 ni -3 ga bo‘ling.

$$x=25$$
