3d+d-7=25/4 eching

$$3 d + d - 7 = \frac { 25 } { 4 }$$

d uchun yechish

$$d = \frac{53}{16} = 3\frac{5}{16} = 3,3125$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

4d ni olish uchun 3d va d ni birlashtirish.

$$4d-7=\frac{25}{4}$$

7 ni ikki tarafga qo’shing.

$$4d=\frac{25}{4}+7$$

7 ni \frac{28}{4} kasrga o‘giring.

$$4d=\frac{25}{4}+\frac{28}{4}$$

\frac{25}{4} va \frac{28}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$4d=\frac{25+28}{4}$$

53 olish uchun 25 va 28'ni qo'shing.

$$4d=\frac{53}{4}$$

Ikki tarafini 4 ga bo‘ling.

$$d=\frac{\frac{53}{4}}{4}$$

\frac{\frac{53}{4}}{4} ni yagona kasrga aylantiring.

$$d=\frac{53}{4\times 4}$$

16 hosil qilish uchun 4 va 4 ni ko'paytirish.

$$d=\frac{53}{16}$$
