8(x-42)=4 eching

$$8(x-42)=4$$

x uchun yechish

$$x = \frac{85}{2} = 42\frac{1}{2} = 42,5$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikki tarafini 8 ga bo‘ling.

$$x-42=\frac{4}{8}$$

\frac{4}{8} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x-42=\frac{1}{2}$$

42 ni ikki tarafga qo’shing.

$$x=\frac{1}{2}+42$$

42 ni \frac{84}{2} kasrga o‘giring.

$$x=\frac{1}{2}+\frac{84}{2}$$

\frac{1}{2} va \frac{84}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$x=\frac{1+84}{2}$$

85 olish uchun 1 va 84'ni qo'shing.

$$x=\frac{85}{2}$$
