2x-7/3=4/15 eching

$$\frac { 2 x - 7 } { 3 } = \frac { 4 } { 15 }$$

x uchun yechish

$$x = \frac{39}{10} = 3\frac{9}{10} = 3,9$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafini 3 ga ko‘paytiring.

$$2x-7=\frac{4}{15}\times 3$$

\frac{4}{15}\times 3 ni yagona kasrga aylantiring.

$$2x-7=\frac{4\times 3}{15}$$

12 hosil qilish uchun 4 va 3 ni ko'paytirish.

$$2x-7=\frac{12}{15}$$

\frac{12}{15} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$2x-7=\frac{4}{5}$$

7 ni ikki tarafga qo’shing.

$$2x=\frac{4}{5}+7$$

7 ni \frac{35}{5} kasrga o‘giring.

$$2x=\frac{4}{5}+\frac{35}{5}$$

\frac{4}{5} va \frac{35}{5} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$2x=\frac{4+35}{5}$$

39 olish uchun 4 va 35'ni qo'shing.

$$2x=\frac{39}{5}$$

Ikki tarafini 2 ga bo‘ling.

$$x=\frac{\frac{39}{5}}{2}$$

\frac{\frac{39}{5}}{2} ni yagona kasrga aylantiring.

$$x=\frac{39}{5\times 2}$$

10 hosil qilish uchun 5 va 2 ni ko'paytirish.

$$x=\frac{39}{10}$$
