5\times 2\left(x+5\right)+30=3\times 4x
Tenglamaning ikkala tarafini 15 ga, 3,5 ning eng kichik karralisiga ko‘paytiring.
10\left(x+5\right)+30=3\times 4x
10 hosil qilish uchun 5 va 2 ni ko'paytirish.
10x+50+30=3\times 4x
10 ga x+5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
10x+80=3\times 4x
80 olish uchun 50 va 30'ni qo'shing.
10x+80=12x
12 hosil qilish uchun 3 va 4 ni ko'paytirish.
10x+80-12x=0
Ikkala tarafdan 12x ni ayirish.
-2x+80=0
-2x ni olish uchun 10x va -12x ni birlashtirish.
-2x=-80
Ikkala tarafdan 80 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
x=\frac{-80}{-2}
Ikki tarafini -2 ga bo‘ling.
x=40
40 ni olish uchun -80 ni -2 ga bo‘ling.
