3y-2=7/10 eching

$$3 y - 2 = \frac { 7 } { 10 }$$

y uchun yechish

$$y=\frac{9}{10}=0,9$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

2 ni ikki tarafga qo’shing.

$$3y=\frac{7}{10}+2$$

2 ni \frac{20}{10} kasrga o‘giring.

$$3y=\frac{7}{10}+\frac{20}{10}$$

\frac{7}{10} va \frac{20}{10} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$3y=\frac{7+20}{10}$$

27 olish uchun 7 va 20'ni qo'shing.

$$3y=\frac{27}{10}$$

Ikki tarafini 3 ga bo‘ling.

$$y=\frac{\frac{27}{10}}{3}$$

\frac{\frac{27}{10}}{3} ni yagona kasrga aylantiring.

$$y=\frac{27}{10\times 3}$$

30 hosil qilish uchun 10 va 3 ni ko'paytirish.

$$y=\frac{27}{30}$$

\frac{27}{30} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$y=\frac{9}{10}$$
