20x-100-5=10\left(x-9\right)+5
10 ga 2x-10 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
20x-105=10\left(x-9\right)+5
-105 olish uchun -100 dan 5 ni ayirish.
20x-105=10x-90+5
10 ga x-9 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
20x-105=10x-85
-85 olish uchun -90 va 5'ni qo'shing.
20x-105-10x=-85
Ikkala tarafdan 10x ni ayirish.
10x-105=-85
10x ni olish uchun 20x va -10x ni birlashtirish.
10x=-85+105
105 ni ikki tarafga qo’shing.
10x=20
20 olish uchun -85 va 105'ni qo'shing.
x=\frac{20}{10}
Ikki tarafini 10 ga bo‘ling.
x=2
2 ni olish uchun 20 ni 10 ga bo‘ling.
