4x+y+2=0 eching

$$4 x + y + 2 = 0$$

x uchun yechish

$$x=-\frac{y}{4}-\frac{1}{2}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$4x+2=-y$$

Ikkala tarafdan 2 ni ayirish.

$$4x=-y-2$$

Ikki tarafini 4 ga bo‘ling.

$$\frac{4x}{4}=\frac{-y-2}{4}$$

4 ga bo'lish 4 ga ko'paytirishni bekor qiladi.

$$x=\frac{-y-2}{4}$$

-y-2 ni 4 ga bo'lish.

$$x=-\frac{y}{4}-\frac{1}{2}$$

y uchun yechish

$$y=-4x-2$$

Yechim qadamlari

Ikkala tarafdan 4x ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$y+2=-4x$$

Ikkala tarafdan 2 ni ayirish.

$$y=-4x-2$$
