2\left(3x+5\right)-\left(2x-1\right)=4
Tenglamaning ikkala tarafini 4 ga, 2,4 ning eng kichik karralisiga ko‘paytiring.
6x+10-\left(2x-1\right)=4
2 ga 3x+5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
6x+10-2x-\left(-1\right)=4
2x-1 teskarisini topish uchun har birining teskarisini toping.
6x+10-2x+1=4
-1 ning teskarisi 1 ga teng.
4x+10+1=4
4x ni olish uchun 6x va -2x ni birlashtirish.
4x+11=4
11 olish uchun 10 va 1'ni qo'shing.
4x=4-11
Ikkala tarafdan 11 ni ayirish.
4x=-7
-7 olish uchun 4 dan 11 ni ayirish.
x=\frac{-7}{4}
Ikki tarafini 4 ga bo‘ling.
x=-\frac{7}{4}
\frac{-7}{4} kasri manfiy belgini olib tashlash bilan -\frac{7}{4} sifatida qayta yozilishi mumkin.
