15x1000+2left(20-xright)1000=45000 eching

$$15x1000+2 \left( 20-x \right) 1000 = 45000$$

x uchun yechish

$$x=\frac{3x_{1000}}{400}-\frac{5}{2}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

2000 hosil qilish uchun 2 va 1000 ni ko'paytirish.

$$15x_{1000}+2000\left(20-x\right)=45000$$

2000 ga 20-x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$15x_{1000}[phone]x=45000$$

Ikkala tarafdan 15x_{1000} ni ayirish.

$$40000-2000x=45000-15x_{1000}$$

Ikkala tarafdan 40000 ni ayirish.

$$-2000x=45000-15x_{1000}-40000$$

5000 olish uchun 45000 dan 40000 ni ayirish.

$$-2000x=5000-15x_{1000}$$

Ikki tarafini -2000 ga bo‘ling.

$$\frac{-2000x}{-2000}=\frac{5000-15x_{1000}}{-2000}$$

-2000 ga bo'lish -2000 ga ko'paytirishni bekor qiladi.

$$x=\frac{5000-15x_{1000}}{-2000}$$

5000-15x_{1000} ni -2000 ga bo'lish.

$$x=\frac{3x_{1000}}{400}-\frac{5}{2}$$

x_1000 uchun yechish

$$x_{1000}=\frac{400x+1000}{3}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

2000 hosil qilish uchun 2 va 1000 ni ko'paytirish.

$$15x_{1000}+2000\left(20-x\right)=45000$$

2000 ga 20-x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$15x_{1000}[phone]x=45000$$

Ikkala tarafdan 40000 ni ayirish.

$$15x_{1000}-2000x=45000-40000$$

5000 olish uchun 45000 dan 40000 ni ayirish.

$$15x_{1000}-2000x=5000$$

2000x ni ikki tarafga qo’shing.

$$15x_{1000}=5000+2000x$$

Tenglama standart shaklda.

$$15x_{1000}=2000x+5000$$

Ikki tarafini 15 ga bo‘ling.

$$\frac{15x_{1000}}{15}=\frac{2000x+5000}{15}$$

15 ga bo'lish 15 ga ko'paytirishni bekor qiladi.

$$x_{1000}=\frac{2000x+5000}{15}$$

5000+2000x ni 15 ga bo'lish.

$$x_{1000}=\frac{400x+1000}{3}$$
