2(x-4)=1 eching

$$2 ( x - 4 ) = 1$$

x uchun yechish

$$x = \frac{9}{2} = 4\frac{1}{2} = 4,5$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikki tarafini 2 ga bo‘ling.

$$x-4=\frac{1}{2}$$

4 ni ikki tarafga qo’shing.

$$x=\frac{1}{2}+4$$

4 ni \frac{8}{2} kasrga o‘giring.

$$x=\frac{1}{2}+\frac{8}{2}$$

\frac{1}{2} va \frac{8}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$x=\frac{1+8}{2}$$

9 olish uchun 1 va 8'ni qo'shing.

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