67*10^2-67*x*10+x=0 eching

$$67 \times { 10 }^{ 2 } -67 \times x \times 10+x = 0$$

x uchun yechish

$$x = \frac{6700}{669} = 10\frac{10}{669} \approx 10,014947683$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

2 daraja ko‘rsatkichini 10 ga hisoblang va 100 ni qiymatni oling.

$$67\times 100-67x\times 10+x=0$$

6700 hosil qilish uchun 67 va 100 ni ko'paytirish.

$$6700-67x\times 10+x=0$$

670 hosil qilish uchun 67 va 10 ni ko'paytirish.

$$6700-670x+x=0$$

-669x ni olish uchun -670x va x ni birlashtirish.

$$6700-669x=0$$

Ikkala tarafdan 6700 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-669x=-6700$$

Ikki tarafini -669 ga bo‘ling.

$$x=\frac{-6700}{-669}$$

Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-6700}{-669} kasrini \frac{6700}{669} ga soddalashtirish mumkin.

$$x=\frac{6700}{669}$$
