2x1+5x2=-3 eching

$$2x1+5x2=-3$$

x_1 uchun yechish

$$x_{1}=\frac{-5x_{2}-3}{2}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 5x_{2} ni ayirish.

$$2x_{1}=-3-5x_{2}$$

Tenglama standart shaklda.

$$2x_{1}=-5x_{2}-3$$

Ikki tarafini 2 ga bo‘ling.

$$\frac{2x_{1}}{2}=\frac{-5x_{2}-3}{2}$$

2 ga bo'lish 2 ga ko'paytirishni bekor qiladi.

$$x_{1}=\frac{-5x_{2}-3}{2}$$

x_2 uchun yechish

$$x_{2}=\frac{-2x_{1}-3}{5}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 2x_{1} ni ayirish.

$$5x_{2}=-3-2x_{1}$$

Tenglama standart shaklda.

$$5x_{2}=-2x_{1}-3$$

Ikki tarafini 5 ga bo‘ling.

$$\frac{5x_{2}}{5}=\frac{-2x_{1}-3}{5}$$

5 ga bo'lish 5 ga ko'paytirishni bekor qiladi.

$$x_{2}=\frac{-2x_{1}-3}{5}$$
