y=2x+y+2 eching

$$y = 2 x + y + 2$$

x uchun yechish

$$x=-1$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$2x+y+2=y$$

Ikkala tarafdan y ni ayirish.

$$2x+2=y-y$$

0 ni olish uchun y va -y ni birlashtirish.

$$2x+2=0$$

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

$$2x=-2$$

Ikki tarafini 2 ga bo‘ling.

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

-1 ni olish uchun -2 ni 2 ga bo‘ling.

$$x=-1$$

y uchun yechish

$$y\in \mathrm{R}$$
