12left(18-xright)=27 eching

$$12 \left( 18-x \right) = 27$$

x uchun yechish

$$x = \frac{63}{4} = 15\frac{3}{4} = 15,75$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikki tarafini 12 ga bo‘ling.

$$18-x=\frac{27}{12}$$

\frac{27}{12} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$18-x=\frac{9}{4}$$

Ikkala tarafdan 18 ni ayirish.

$$-x=\frac{9}{4}-18$$

18 ni \frac{72}{4} kasrga o‘giring.

$$-x=\frac{9}{4}-\frac{72}{4}$$

\frac{9}{4} va \frac{72}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$-x=\frac{9-72}{4}$$

-63 olish uchun 9 dan 72 ni ayirish.

$$-x=-\frac{63}{4}$$

Ikkala tarafini -1 ga ko‘paytiring.

$$x=\frac{63}{4}$$
