2-9-10z+3-8z=z-9+3z+10-10z eching

$$2 - 9 - 10 z + 3 - 8 z = z - 9 + 3 z + 10 - 10 z$$

z uchun yechish

$$z=-\frac{5}{12}\approx -0,416666667$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-7 olish uchun 2 dan 9 ni ayirish.

$$-7-10z+3-8z=z-9+3z+10-10z$$

-4 olish uchun -7 va 3'ni qo'shing.

$$-4-10z-8z=z-9+3z+10-10z$$

-18z ni olish uchun -10z va -8z ni birlashtirish.

$$-4-18z=z-9+3z+10-10z$$

4z ni olish uchun z va 3z ni birlashtirish.

$$-4-18z=4z-9+10-10z$$

1 olish uchun -9 va 10'ni qo'shing.

$$-4-18z=4z+1-10z$$

-6z ni olish uchun 4z va -10z ni birlashtirish.

$$-4-18z=-6z+1$$

6z ni ikki tarafga qo’shing.

$$-4-18z+6z=1$$

-12z ni olish uchun -18z va 6z ni birlashtirish.

$$-4-12z=1$$

4 ni ikki tarafga qo’shing.

$$-12z=1+4$$

5 olish uchun 1 va 4'ni qo'shing.

$$-12z=5$$

Ikki tarafini -12 ga bo‘ling.

$$z=\frac{5}{-12}$$

\frac{5}{-12} kasri manfiy belgini olib tashlash bilan -\frac{5}{12} sifatida qayta yozilishi mumkin.

$$z=-\frac{5}{12}$$
