2(2x-1)=9 eching

$$2 ( 2 x - 1 ) = 9$$

x uchun yechish

$$x = \frac{11}{4} = 2\frac{3}{4} = 2,75$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikki tarafini 2 ga bo‘ling.

$$2x-1=\frac{9}{2}$$

1 ni ikki tarafga qo’shing.

$$2x=\frac{9}{2}+1$$

1 ni \frac{2}{2} kasrga o‘giring.

$$2x=\frac{9}{2}+\frac{2}{2}$$

\frac{9}{2} va \frac{2}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$2x=\frac{9+2}{2}$$

11 olish uchun 9 va 2'ni qo'shing.

$$2x=\frac{11}{2}$$

Ikki tarafini 2 ga bo‘ling.

$$x=\frac{\frac{11}{2}}{2}$$

\frac{\frac{11}{2}}{2} ni yagona kasrga aylantiring.

$$x=\frac{11}{2\times 2}$$

4 hosil qilish uchun 2 va 2 ni ko'paytirish.

$$x=\frac{11}{4}$$
