5x-5+6=13x-\left(x-8\right)
5 ga x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
5x+1=13x-\left(x-8\right)
1 olish uchun -5 va 6'ni qo'shing.
5x+1=13x-x-\left(-8\right)
x-8 teskarisini topish uchun har birining teskarisini toping.
5x+1=13x-x+8
-8 ning teskarisi 8 ga teng.
5x+1=12x+8
12x ni olish uchun 13x va -x ni birlashtirish.
5x+1-12x=8
Ikkala tarafdan 12x ni ayirish.
-7x+1=8
-7x ni olish uchun 5x va -12x ni birlashtirish.
-7x=8-1
Ikkala tarafdan 1 ni ayirish.
-7x=7
7 olish uchun 8 dan 1 ni ayirish.
x=\frac{7}{-7}
Ikki tarafini -7 ga bo‘ling.
x=-1
-1 ni olish uchun 7 ni -7 ga bo‘ling.
