10-2x+6=3x-4\left(5-x\right)
-2 ga x-3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
16-2x=3x-4\left(5-x\right)
16 olish uchun 10 va 6'ni qo'shing.
16-2x=3x-20+4x
-4 ga 5-x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
16-2x=7x-20
7x ni olish uchun 3x va 4x ni birlashtirish.
16-2x-7x=-20
Ikkala tarafdan 7x ni ayirish.
16-9x=-20
-9x ni olish uchun -2x va -7x ni birlashtirish.
-9x=-20-16
Ikkala tarafdan 16 ni ayirish.
-9x=-36
-36 olish uchun -20 dan 16 ni ayirish.
x=\frac{-36}{-9}
Ikki tarafini -9 ga bo‘ling.
x=4
4 ni olish uchun -36 ni -9 ga bo‘ling.
