x uchun yechish

$$x=-y-z$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

y+z teskarisini topish uchun har birining teskarisini toping.

$$-y-z-\left(y+x\right)-\left(x+z\right)=0$$

y+x teskarisini topish uchun har birining teskarisini toping.

$$-y-z-y-x-\left(x+z\right)=0$$

-2y ni olish uchun -y va -y ni birlashtirish.

$$-2y-z-x-\left(x+z\right)=0$$

x+z teskarisini topish uchun har birining teskarisini toping.

$$-2y-z-x-x-z=0$$

-2x ni olish uchun -x va -x ni birlashtirish.

$$-2y-z-2x-z=0$$

-2z ni olish uchun -z va -z ni birlashtirish.

$$-2y-2z-2x=0$$

2y ni ikki tarafga qo’shing. Har qanday songa nolni qo‘shsangiz, o‘zi chiqadi.

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

2z ni ikki tarafga qo’shing.

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

Ikki tarafini -2 ga bo‘ling.

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

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

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

2y+2z ni -2 ga bo'lish.

$$x=-\left(y+z\right)$$

y uchun yechish

$$y=-x-z$$

y+z teskarisini topish uchun har birining teskarisini toping.

$$-y-z-\left(y+x\right)-\left(x+z\right)=0$$

y+x teskarisini topish uchun har birining teskarisini toping.

$$-y-z-y-x-\left(x+z\right)=0$$

-2y ni olish uchun -y va -y ni birlashtirish.

$$-2y-z-x-\left(x+z\right)=0$$

x+z teskarisini topish uchun har birining teskarisini toping.

$$-2y-z-x-x-z=0$$

-2x ni olish uchun -x va -x ni birlashtirish.

$$-2y-z-2x-z=0$$

-2z ni olish uchun -z va -z ni birlashtirish.

$$-2y-2z-2x=0$$

2z ni ikki tarafga qo’shing. Har qanday songa nolni qo‘shsangiz, o‘zi chiqadi.

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

2x ni ikki tarafga qo’shing.

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

Tenglama standart shaklda.

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

Ikki tarafini -2 ga bo‘ling.

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

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

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

2z+2x ni -2 ga bo'lish.

$$y=-\left(x+z\right)$$
