2\left(x+17\right)=3\left(x+7\right)
x qiymati -7 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 2\left(x+7\right) ga, x+8-1,2 ning eng kichik karralisiga ko‘paytiring.
2x+34=3\left(x+7\right)
2 ga x+17 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2x+34=3x+21
3 ga x+7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2x+34-3x=21
Ikkala tarafdan 3x ni ayirish.
-x+34=21
-x ni olish uchun 2x va -3x ni birlashtirish.
-x=21-34
Ikkala tarafdan 34 ni ayirish.
-x=-13
-13 olish uchun 21 dan 34 ni ayirish.
x=13
Ikkala tarafini -1 ga ko‘paytiring.
