4\times 3x-2\left(x-2\right)=40+x
Tenglamaning ikkala tarafini 8 ga, 2,4,8 ning eng kichik karralisiga ko‘paytiring.
12x-2\left(x-2\right)=40+x
12 hosil qilish uchun 4 va 3 ni ko'paytirish.
12x-2x+4=40+x
-2 ga x-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
10x+4=40+x
10x ni olish uchun 12x va -2x ni birlashtirish.
10x+4-x=40
Ikkala tarafdan x ni ayirish.
9x+4=40
9x ni olish uchun 10x va -x ni birlashtirish.
9x=40-4
Ikkala tarafdan 4 ni ayirish.
9x=36
36 olish uchun 40 dan 4 ni ayirish.
x=\frac{36}{9}
Ikki tarafini 9 ga bo‘ling.
x=4
4 ni olish uchun 36 ni 9 ga bo‘ling.
