16-6x-\left(2^{7}-7x\right)=12-\left(5-2x\right)
2 ga 8-3x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
16-6x-\left(128-7x\right)=12-\left(5-2x\right)
7 daraja ko‘rsatkichini 2 ga hisoblang va 128 ni qiymatni oling.
16-6x-128-\left(-7x\right)=12-\left(5-2x\right)
128-7x teskarisini topish uchun har birining teskarisini toping.
16-6x-128+7x=12-\left(5-2x\right)
-7x ning teskarisi 7x ga teng.
-112-6x+7x=12-\left(5-2x\right)
-112 olish uchun 16 dan 128 ni ayirish.
-112+x=12-\left(5-2x\right)
x ni olish uchun -6x va 7x ni birlashtirish.
-112+x=12-5-\left(-2x\right)
5-2x teskarisini topish uchun har birining teskarisini toping.
-112+x=12-5+2x
-2x ning teskarisi 2x ga teng.
-112+x=7+2x
7 olish uchun 12 dan 5 ni ayirish.
-112+x-2x=7
Ikkala tarafdan 2x ni ayirish.
-112-x=7
-x ni olish uchun x va -2x ni birlashtirish.
-x=7+112
112 ni ikki tarafga qo’shing.
-x=119
119 olish uchun 7 va 112'ni qo'shing.
x=-119
Ikkala tarafini -1 ga ko‘paytiring.
