6\left(6x-8\right)+4\left(5x-4\right)-3\left(4x-2\right)=30
Tenglamaning ikkala tarafini 12 ga, 2,3,4 ning eng kichik karralisiga ko‘paytiring.
36x-48+4\left(5x-4\right)-3\left(4x-2\right)=30
6 ga 6x-8 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
36x-48+20x-16-3\left(4x-2\right)=30
4 ga 5x-4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
56x-48-16-3\left(4x-2\right)=30
56x ni olish uchun 36x va 20x ni birlashtirish.
56x-64-3\left(4x-2\right)=30
-64 olish uchun -48 dan 16 ni ayirish.
56x-64-12x+6=30
-3 ga 4x-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
44x-64+6=30
44x ni olish uchun 56x va -12x ni birlashtirish.
44x-58=30
-58 olish uchun -64 va 6'ni qo'shing.
44x=30+58
58 ni ikki tarafga qo’shing.
44x=88
88 olish uchun 30 va 58'ni qo'shing.
x=\frac{88}{44}
Ikki tarafini 44 ga bo‘ling.
x=2
2 ni olish uchun 88 ni 44 ga bo‘ling.
