10a=r/d eching

$$10 a = \frac { r } { d }$$

a uchun yechish

$$a=\frac{r}{10d}$$

$$d\neq 0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini d ga ko'paytirish.

$$10ad=r$$

Tenglama standart shaklda.

$$10da=r$$

Ikki tarafini 10d ga bo‘ling.

$$\frac{10da}{10d}=\frac{r}{10d}$$

10d ga bo'lish 10d ga ko'paytirishni bekor qiladi.

$$a=\frac{r}{10d}$$

d uchun yechish

$$\left\{\begin{matrix}d=\frac{r}{10a}\text{, }&r\neq 0\text{ and }a\neq 0\\d\neq 0\text{, }&a=0\text{ and }r=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

d qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini d ga ko'paytirish.

$$10ad=r$$

Ikki tarafini 10a ga bo‘ling.

$$\frac{10ad}{10a}=\frac{r}{10a}$$

10a ga bo'lish 10a ga ko'paytirishni bekor qiladi.

$$d=\frac{r}{10a}$$

d qiymati 0 teng bo‘lmaydi.

$$d=\frac{r}{10a}\text{, }d\neq 0$$
