2\left(5x-6\right)-3\left(4x-7\right)=19-2\left(4x-10\right)
Tenglamaning ikkala tarafini 6 ga, 3,2,6 ning eng kichik karralisiga ko‘paytiring.
10x-12-3\left(4x-7\right)=19-2\left(4x-10\right)
2 ga 5x-6 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
10x-12-12x+21=19-2\left(4x-10\right)
-3 ga 4x-7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-2x-12+21=19-2\left(4x-10\right)
-2x ni olish uchun 10x va -12x ni birlashtirish.
-2x+9=19-2\left(4x-10\right)
9 olish uchun -12 va 21'ni qo'shing.
-2x+9=19-8x+20
-2 ga 4x-10 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-2x+9=39-8x
39 olish uchun 19 va 20'ni qo'shing.
-2x+9+8x=39
8x ni ikki tarafga qo’shing.
6x+9=39
6x ni olish uchun -2x va 8x ni birlashtirish.
6x=39-9
Ikkala tarafdan 9 ni ayirish.
6x=30
30 olish uchun 39 dan 9 ni ayirish.
x=\frac{30}{6}
Ikki tarafini 6 ga bo‘ling.
x=5
5 ni olish uchun 30 ni 6 ga bo‘ling.
