r(2-d)/y=c eching

$$\frac { r ( 2 - d ) } { y } = c$$

c uchun yechish

$$c=\frac{r\left(2-d\right)}{y}$$

$$y\neq 0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini y ga ko'paytirish.

$$r\left(2-d\right)=cy$$

r ga 2-d ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$2r-rd=cy$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$cy=2r-rd$$

Tenglama standart shaklda.

$$yc=2r-dr$$

Ikki tarafini y ga bo‘ling.

$$\frac{yc}{y}=\frac{r\left(2-d\right)}{y}$$

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

$$c=\frac{r\left(2-d\right)}{y}$$

d uchun yechish

$$\left\{\begin{matrix}d=-\frac{cy}{r}+2\text{, }&r\neq 0\text{ and }y\neq 0\\d\in \mathrm{R}\text{, }&c=0\text{ and }r=0\text{ and }y\neq 0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini y ga ko'paytirish.

$$r\left(2-d\right)=cy$$

r ga 2-d ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$2r-rd=cy$$

Ikkala tarafdan 2r ni ayirish.

$$-rd=cy-2r$$

Tenglama standart shaklda.

$$\left(-r\right)d=cy-2r$$

Ikki tarafini -r ga bo‘ling.

$$\frac{\left(-r\right)d}{-r}=\frac{cy-2r}{-r}$$

-r ga bo'lish -r ga ko'paytirishni bekor qiladi.

$$d=\frac{cy-2r}{-r}$$

cy-2r ni -r ga bo'lish.

$$d=-\frac{cy}{r}+2$$
