x\times 175=\left(x+15\right)\times 140
x qiymati -15,0 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini x\left(x+15\right) ga, x+15,x ning eng kichik karralisiga ko‘paytiring.
x\times 175=140x+2100
x+15 ga 140 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
x\times 175-140x=2100
Ikkala tarafdan 140x ni ayirish.
35x=2100
35x ni olish uchun x\times 175 va -140x ni birlashtirish.
x=\frac{2100}{35}
Ikki tarafini 35 ga bo‘ling.
x=60
60 ni olish uchun 2100 ni 35 ga bo‘ling.
