9x-5x-1-\left(2+8x-\left(7x-5\right)\right)+9x=0
5x+1 teskarisini topish uchun har birining teskarisini toping.
4x-1-\left(2+8x-\left(7x-5\right)\right)+9x=0
4x ni olish uchun 9x va -5x ni birlashtirish.
4x-1-\left(2+8x-7x-\left(-5\right)\right)+9x=0
7x-5 teskarisini topish uchun har birining teskarisini toping.
4x-1-\left(2+8x-7x+5\right)+9x=0
-5 ning teskarisi 5 ga teng.
4x-1-\left(2+x+5\right)+9x=0
x ni olish uchun 8x va -7x ni birlashtirish.
4x-1-\left(7+x\right)+9x=0
7 olish uchun 2 va 5'ni qo'shing.
4x-1-7-x+9x=0
7+x teskarisini topish uchun har birining teskarisini toping.
4x-8-x+9x=0
-8 olish uchun -1 dan 7 ni ayirish.
3x-8+9x=0
3x ni olish uchun 4x va -x ni birlashtirish.
12x-8=0
12x ni olish uchun 3x va 9x ni birlashtirish.
12x=8
8 ni ikki tarafga qo’shing. Har qanday songa nolni qo‘shsangiz, o‘zi chiqadi.
x=\frac{8}{12}
Ikki tarafini 12 ga bo‘ling.
x=\frac{2}{3}
\frac{8}{12} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
