4\left(x-2\right)-3\left(x+1\right)=48
Tenglamaning ikkala tarafini 12 ga, 3,4 ning eng kichik karralisiga ko‘paytiring.
4x-8-3\left(x+1\right)=48
4 ga x-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
4x-8-3x-3=48
-3 ga x+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
x-8-3=48
x ni olish uchun 4x va -3x ni birlashtirish.
x-11=48
-11 olish uchun -8 dan 3 ni ayirish.
x=48+11
11 ni ikki tarafga qo’shing.
x=59
59 olish uchun 48 va 11'ni qo'shing.
