8x-4-\left(3x+4\right)=5x-8
4 ga 2x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
8x-4-3x-4=5x-8
3x+4 teskarisini topish uchun har birining teskarisini toping.
5x-4-4=5x-8
5x ni olish uchun 8x va -3x ni birlashtirish.
5x-8=5x-8
-8 olish uchun -4 dan 4 ni ayirish.
5x-8-5x=-8
Ikkala tarafdan 5x ni ayirish.
-8=-8
0 ni olish uchun 5x va -5x ni birlashtirish.
\text{true}
-8 va -8 ni taqqoslang.
