x=117*90-13*9^2/2 eching

$$x = 117 \times 90 - 13 \times 9 ^ { 2 } / 2$$

x uchun yechish

$$x = \frac{20007}{2} = 10003\frac{1}{2} = 10003,5$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

10530 hosil qilish uchun 117 va 90 ni ko'paytirish.

$$x=10530-\frac{13\times 9^{2}}{2}$$

2 daraja ko‘rsatkichini 9 ga hisoblang va 81 ni qiymatni oling.

$$x=10530-\frac{13\times 81}{2}$$

1053 hosil qilish uchun 13 va 81 ni ko'paytirish.

$$x=10530-\frac{1053}{2}$$

10530 ni \frac{21060}{2} kasrga o‘giring.

$$x=\frac{21060}{2}-\frac{1053}{2}$$

\frac{21060}{2} va \frac{1053}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$x=\frac{21060-1053}{2}$$

20007 olish uchun 21060 dan 1053 ni ayirish.

$$x=\frac{20007}{2}$$

x'ni tayinlash

$$x≔\frac{20007}{2}$$
