5-x-\left(-7\right)=9\left(x+8\right)
x-7 teskarisini topish uchun har birining teskarisini toping.
5-x+7=9\left(x+8\right)
-7 ning teskarisi 7 ga teng.
12-x=9\left(x+8\right)
12 olish uchun 5 va 7'ni qo'shing.
12-x=9x+72
9 ga x+8 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
12-x-9x=72
Ikkala tarafdan 9x ni ayirish.
12-10x=72
-10x ni olish uchun -x va -9x ni birlashtirish.
-10x=72-12
Ikkala tarafdan 12 ni ayirish.
-10x=60
60 olish uchun 72 dan 12 ni ayirish.
x=\frac{60}{-10}
Ikki tarafini -10 ga bo‘ling.
x=-6
-6 ni olish uchun 60 ni -10 ga bo‘ling.
