5\left(2x+1\right)=8\left(x+5\right)
x qiymati -5 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 5\left(x+5\right) ga, x+5,5 ning eng kichik karralisiga ko‘paytiring.
10x+5=8\left(x+5\right)
5 ga 2x+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
10x+5=8x+40
8 ga x+5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
10x+5-8x=40
Ikkala tarafdan 8x ni ayirish.
2x+5=40
2x ni olish uchun 10x va -8x ni birlashtirish.
2x=40-5
Ikkala tarafdan 5 ni ayirish.
2x=35
35 olish uchun 40 dan 5 ni ayirish.
x=\frac{35}{2}
Ikki tarafini 2 ga bo‘ling.
