808=-f-\left(-83f\right)-\left(-662\right)
-83f-662 teskarisini topish uchun har birining teskarisini toping.
808=-f+83f-\left(-662\right)
-83f ning teskarisi 83f ga teng.
808=-f+83f+662
-662 ning teskarisi 662 ga teng.
808=82f+662
82f ni olish uchun -f va 83f ni birlashtirish.
82f+662=808
Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.
82f=808-662
Ikkala tarafdan 662 ni ayirish.
82f=146
146 olish uchun 808 dan 662 ni ayirish.
f=\frac{146}{82}
Ikki tarafini 82 ga bo‘ling.
f=\frac{73}{41}
\frac{146}{82} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
