C=3r-100/9 eching

$$C = \frac { 3 r - 100 } { 9 }$$

r uchun yechish

$$r=3C+\frac{100}{3}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{1}{3}r-\frac{100}{9} natijani olish uchun 3r-100 ning har bir ifodasini 9 ga bo‘ling.

$$C=\frac{1}{3}r-\frac{100}{9}$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$\frac{1}{3}r-\frac{100}{9}=C$$

\frac{100}{9} ni ikki tarafga qo’shing.

$$\frac{1}{3}r=C+\frac{100}{9}$$

Ikkala tarafini 3 ga ko‘paytiring.

$$\frac{\frac{1}{3}r}{\frac{1}{3}}=\frac{C+\frac{100}{9}}{\frac{1}{3}}$$

\frac{1}{3} ga bo'lish \frac{1}{3} ga ko'paytirishni bekor qiladi.

$$r=\frac{C+\frac{100}{9}}{\frac{1}{3}}$$

C+\frac{100}{9} ni \frac{1}{3} ga bo'lish C+\frac{100}{9} ga k'paytirish \frac{1}{3} ga qaytarish.

$$r=3C+\frac{100}{3}$$

C uchun yechish

$$C=\frac{r}{3}-\frac{100}{9}$$

Yechim qadamlari

\frac{1}{3}r-\frac{100}{9} natijani olish uchun 3r-100 ning har bir ifodasini 9 ga bo‘ling.

$$C=\frac{1}{3}r-\frac{100}{9}$$
