20(x+2)+8(x-2)=3 eching

$$20 ( x + 2 ) + 8 ( x - 2 ) = 3$$

x uchun yechish

$$x=-\frac{3}{4}=-0,75$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

20 ga x+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$20x+40+8\left(x-2\right)=3$$

8 ga x-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$20x+40+8x-16=3$$

28x ni olish uchun 20x va 8x ni birlashtirish.

$$28x+40-16=3$$

24 olish uchun 40 dan 16 ni ayirish.

$$28x+24=3$$

Ikkala tarafdan 24 ni ayirish.

$$28x=3-24$$

-21 olish uchun 3 dan 24 ni ayirish.

$$28x=-21$$

Ikki tarafini 28 ga bo‘ling.

$$x=\frac{-21}{28}$$

\frac{-21}{28} ulushini 7 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=-\frac{3}{4}$$
