5x-15+4\left(x+5\right)=20\left(x-8\right)
5 ga x-3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
5x-15+4x+20=20\left(x-8\right)
4 ga x+5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
9x-15+20=20\left(x-8\right)
9x ni olish uchun 5x va 4x ni birlashtirish.
9x+5=20\left(x-8\right)
5 olish uchun -15 va 20'ni qo'shing.
9x+5=20x-160
20 ga x-8 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
9x+5-20x=-160
Ikkala tarafdan 20x ni ayirish.
-11x+5=-160
-11x ni olish uchun 9x va -20x ni birlashtirish.
-11x=-160-5
Ikkala tarafdan 5 ni ayirish.
-11x=-165
-165 olish uchun -160 dan 5 ni ayirish.
x=\frac{-165}{-11}
Ikki tarafini -11 ga bo‘ling.
x=15
15 ni olish uchun -165 ni -11 ga bo‘ling.
