3b+1=4b+16
b qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 3b ga ko'paytirish.
3b+1-4b=16
Ikkala tarafdan 4b ni ayirish.
-b+1=16
-b ni olish uchun 3b va -4b ni birlashtirish.
-b=16-1
Ikkala tarafdan 1 ni ayirish.
-b=15
15 olish uchun 16 dan 1 ni ayirish.
b=-15
Ikkala tarafini -1 ga ko‘paytiring.
