EdP=750-1000/1000*100/125-100 eching

$$E d P = \frac { 750 - 1000 } { 1000 } \times \frac { 100 } { 125 - 100 }$$

E uchun yechish

$$E=-\frac{1}{Pd}$$

$$P\neq 0\text{ and }d\neq 0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-250 olish uchun 750 dan 1000 ni ayirish.

$$EdP=\frac{-250}{1000}\times \left(\frac{100}{125-100}\right)$$

\frac{-250}{1000} ulushini 250 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$EdP=\left(-\frac{1}{4}\right)\times \left(\frac{100}{125-100}\right)$$

25 olish uchun 125 dan 100 ni ayirish.

$$EdP=\left(-\frac{1}{4}\right)\times \left(\frac{100}{25}\right)$$

4 ni olish uchun 100 ni 25 ga bo‘ling.

$$EdP=\left(-\frac{1}{4}\right)\times 4$$

Tenglama standart shaklda.

$$PdE=-1$$

Ikki tarafini dP ga bo‘ling.

$$\frac{PdE}{Pd}=-\frac{1}{Pd}$$

dP ga bo'lish dP ga ko'paytirishni bekor qiladi.

$$E=-\frac{1}{Pd}$$

P uchun yechish

$$P=-\frac{1}{Ed}$$

$$d\neq 0\text{ and }E\neq 0$$

25 olish uchun 125 dan 100 ni ayirish.

$$EdP=\left(-\frac{1}{4}\right)\times \left(\frac{100}{25}\right)$$

4 ni olish uchun 100 ni 25 ga bo‘ling.

$$EdP=\left(-\frac{1}{4}\right)\times 4$$

Tenglama standart shaklda.

$$EdP=-1$$

Ikki tarafini Ed ga bo‘ling.

$$\frac{EdP}{Ed}=-\frac{1}{Ed}$$

Ed ga bo'lish Ed ga ko'paytirishni bekor qiladi.

$$P=-\frac{1}{Ed}$$
