Klipbordga nusxa olish
3-2x=16
3 olish uchun 1 va 2'ni qo'shing.
-2x=16-3
Ikkala tarafdan 3 ni ayirish.
-2x=13
13 olish uchun 16 dan 3 ni ayirish.
x=\frac{13}{-2}
Ikki tarafini -2 ga bo‘ling.
x=-\frac{13}{2}
\frac{13}{-2} kasri manfiy belgini olib tashlash bilan -\frac{13}{2} sifatida qayta yozilishi mumkin.
