2\left(x-6\right)-3\left(x-4\right)=2\left(x+5\right)
Tenglamaning ikkala tarafini 6 ga, 3,2 ning eng kichik karralisiga ko‘paytiring.
2x-12-3\left(x-4\right)=2\left(x+5\right)
2 ga x-6 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2x-12-3x+12=2\left(x+5\right)
-3 ga x-4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-x-12+12=2\left(x+5\right)
-x ni olish uchun 2x va -3x ni birlashtirish.
-x=2\left(x+5\right)
0 olish uchun -12 va 12'ni qo'shing.
-x=2x+10
2 ga x+5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-x-2x=10
Ikkala tarafdan 2x ni ayirish.
-3x=10
-3x ni olish uchun -x va -2x ni birlashtirish.
x=\frac{10}{-3}
Ikki tarafini -3 ga bo‘ling.
x=-\frac{10}{3}
\frac{10}{-3} kasri manfiy belgini olib tashlash bilan -\frac{10}{3} sifatida qayta yozilishi mumkin.
