5\left(x+1\right)-3\left(x-2\right)=30
Tenglamaning ikkala tarafini 15 ga, 3,5 ning eng kichik karralisiga ko‘paytiring.
5x+5-3\left(x-2\right)=30
5 ga x+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
5x+5-3x+6=30
-3 ga x-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2x+5+6=30
2x ni olish uchun 5x va -3x ni birlashtirish.
2x+11=30
11 olish uchun 5 va 6'ni qo'shing.
2x=30-11
Ikkala tarafdan 11 ni ayirish.
2x=19
19 olish uchun 30 dan 11 ni ayirish.
x=\frac{19}{2}
