z uchun yechish
z = -\frac{13}{2} = -6\frac{1}{2} = -6,5
Baham ko'rish
Klipbordga nusxa olish
8z-5=10z+8
8z ni olish uchun 20z va -12z ni birlashtirish.
8z-5-10z=8
Ikkala tarafdan 10z ni ayirish.
-2z-5=8
-2z ni olish uchun 8z va -10z ni birlashtirish.
-2z=8+5
5 ni ikki tarafga qo’shing.
-2z=13
13 olish uchun 8 va 5'ni qo'shing.
z=\frac{13}{-2}
Ikki tarafini -2 ga bo‘ling.
z=-\frac{13}{2}
\frac{13}{-2} kasri manfiy belgini olib tashlash bilan -\frac{13}{2} sifatida qayta yozilishi mumkin.
