8-\left(-x\right)-\left(-2\right)=5x-\left(6-9x\right)
-x-2 teskarisini topish uchun har birining teskarisini toping.
8-\left(-x\right)+2=5x-\left(6-9x\right)
-2 ning teskarisi 2 ga teng.
10-\left(-x\right)=5x-\left(6-9x\right)
10 olish uchun 8 va 2'ni qo'shing.
10-\left(-x\right)=5x-6-\left(-9x\right)
6-9x teskarisini topish uchun har birining teskarisini toping.
10-\left(-x\right)=5x-6+9x
-9x ning teskarisi 9x ga teng.
10-\left(-x\right)=14x-6
14x ni olish uchun 5x va 9x ni birlashtirish.
10-\left(-x\right)-14x=-6

-\left(-x\right)-14x=-6-10
Ikkala tarafdan 10 ni ayirish.
-\left(-x\right)-14x=-16
-16 olish uchun -6 dan 10 ni ayirish.
x-14x=-16
1 hosil qilish uchun -1 va -1 ni ko'paytirish.
-13x=-16
-13x ni olish uchun x va -14x ni birlashtirish.
x=\frac{-16}{-13}
