\left(w+10\right)\left(-2\right)=\left(w+5\right)\times 3
w qiymati -10,-5 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini \left(w+5\right)\left(w+10\right) ga, w+5,w+10 ning eng kichik karralisiga ko‘paytiring.
-2w-20=\left(w+5\right)\times 3
w+10 ga -2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-2w-20=3w+15
w+5 ga 3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-2w-20-3w=15
Ikkala tarafdan 3w ni ayirish.
-5w-20=15
-5w ni olish uchun -2w va -3w ni birlashtirish.
-5w=15+20
20 ni ikki tarafga qo’shing.
-5w=35
35 olish uchun 15 va 20'ni qo'shing.
w=\frac{35}{-5}
Ikki tarafini -5 ga bo‘ling.
w=-7
-7 ni olish uchun 35 ni -5 ga bo‘ling.
