f(x)=x/2-3xtext{at}x=2 eching

$$f ( x ) = \frac { x } { 2 - 3 x } \text { at } x = 2$$

f, x uchun yechish

$$x=2$$

$$f=-\frac{1}{4}=-0,25$$

Yechim qadamlari

Birinchi tenglamani yeching. Tenglamaga o‘zgaruvchining ma’lum qiymatlarini joylang.

$$f\times 2=\frac{2}{2-3\times 2}$$

-6 hosil qilish uchun -3 va 2 ni ko'paytirish.

$$f\times 2=\frac{2}{2-6}$$

-4 olish uchun 2 dan 6 ni ayirish.

$$f\times 2=\frac{2}{-4}$$

\frac{2}{-4} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$f\times 2=-\frac{1}{2}$$

Ikki tarafini 2 ga bo‘ling.

$$f=\frac{-\frac{1}{2}}{2}$$

\frac{-\frac{1}{2}}{2} ni yagona kasrga aylantiring.

$$f=\frac{-1}{2\times 2}$$

4 hosil qilish uchun 2 va 2 ni ko'paytirish.

$$f=\frac{-1}{4}$$

\frac{-1}{4} kasri manfiy belgini olib tashlash bilan -\frac{1}{4} sifatida qayta yozilishi mumkin.

$$f=-\frac{1}{4}$$

Tizim hal qilindi.

$$f=-\frac{1}{4} x=2$$
