Baham ko'rish
Klipbordga nusxa olish
100+\left(x-5\right)\times 4=\left(5\times 20+44\right)\times 0\times 9
100 hosil qilish uchun 5 va 20 ni ko'paytirish.
100+4x-20=\left(5\times 20+44\right)\times 0\times 9
x-5 ga 4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
80+4x=\left(5\times 20+44\right)\times 0\times 9
80 olish uchun 100 dan 20 ni ayirish.
80+4x=\left(100+44\right)\times 0\times 9
100 hosil qilish uchun 5 va 20 ni ko'paytirish.
80+4x=144\times 0\times 9
144 olish uchun 100 va 44'ni qo'shing.
80+4x=0\times 9
0 hosil qilish uchun 144 va 0 ni ko'paytirish.
80+4x=0
0 hosil qilish uchun 0 va 9 ni ko'paytirish.
4x=-80
Ikkala tarafdan 80 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
x=\frac{-80}{4}
Ikki tarafini 4 ga bo‘ling.
x=-20
-20 ni olish uchun -80 ni 4 ga bo‘ling.
