3\times 5\left(x+1\right)-2\left(2-3x\right)=74
Tenglamaning ikkala tarafini 6 ga, 2,3 ning eng kichik karralisiga ko‘paytiring.
15\left(x+1\right)-2\left(2-3x\right)=74
15 hosil qilish uchun 3 va 5 ni ko'paytirish.
15x+15-2\left(2-3x\right)=74
15 ga x+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
15x+15-4+6x=74
-2 ga 2-3x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
15x+11+6x=74
11 olish uchun 15 dan 4 ni ayirish.
21x+11=74
21x ni olish uchun 15x va 6x ni birlashtirish.
21x=74-11
Ikkala tarafdan 11 ni ayirish.
21x=63
63 olish uchun 74 dan 11 ni ayirish.
x=\frac{63}{21}
Ikki tarafini 21 ga bo‘ling.
x=3
3 ni olish uchun 63 ni 21 ga bo‘ling.
