\left(5s+4\right)\times 2=\left(s-3\right)\times 9
s qiymati -\frac{4}{5},3 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini \left(s-3\right)\left(5s+4\right) ga, s-3,5s+4 ning eng kichik karralisiga ko‘paytiring.
10s+8=\left(s-3\right)\times 9
5s+4 ga 2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
10s+8=9s-27
s-3 ga 9 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
10s+8-9s=-27
Ikkala tarafdan 9s ni ayirish.
s+8=-27
s ni olish uchun 10s va -9s ni birlashtirish.
s=-27-8
Ikkala tarafdan 8 ni ayirish.
s=-35
-35 olish uchun -27 dan 8 ni ayirish.
