Baham ko'rish
Klipbordga nusxa olish
-4z+32=6z+1
Tenglamaning ikkala tarafini 4 ga ko'paytirish.
-4z+32-6z=1
Ikkala tarafdan 6z ni ayirish.
-10z+32=1
-10z ni olish uchun -4z va -6z ni birlashtirish.
-10z=1-32
Ikkala tarafdan 32 ni ayirish.
-10z=-31
-31 olish uchun 1 dan 32 ni ayirish.
z=\frac{-31}{-10}
Ikki tarafini -10 ga bo‘ling.
z=\frac{31}{10}
Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-31}{-10} kasrini \frac{31}{10} ga soddalashtirish mumkin.
