x+2y+3z=0 eching

$$x + 2 y + 3 z = 0$$

x uchun yechish

$$x=-2y-3z$$

Yechim qadamlari

Ikkala tarafdan 2y ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$x+3z=-2y$$

Ikkala tarafdan 3z ni ayirish.

$$x=-2y-3z$$

y uchun yechish

$$y=\frac{-x-3z}{2}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan x ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$2y+3z=-x$$

Ikkala tarafdan 3z ni ayirish.

$$2y=-x-3z$$

Ikki tarafini 2 ga bo‘ling.

$$\frac{2y}{2}=\frac{-x-3z}{2}$$

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

$$y=\frac{-x-3z}{2}$$
