-9+45c=-\left(-9c+9\right)
-9 ga 1-5c ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-9+45c=-\left(-9c\right)-9
-9c+9 teskarisini topish uchun har birining teskarisini toping.
-9+45c=9c-9
-9c ning teskarisi 9c ga teng.
-9+45c-9c=-9
Ikkala tarafdan 9c ni ayirish.
-9+36c=-9
36c ni olish uchun 45c va -9c ni birlashtirish.
36c=-9+9
9 ni ikki tarafga qo’shing.
36c=0
0 olish uchun -9 va 9'ni qo'shing.
c=0
Ikki son koʻpaytmasi 0 ga teng, agar kamida bittasi 0 bo‘lsa. 36 0 ga teng bo‘lmasa, c 0 ga teng bo‘lishi kerak.
