(x-x10/100)-(x-x10/100)5/100=1539 eching

$$(x-x \frac{ 10 }{ 100 } )-(x-x \frac{ 10 }{ 100 } ) \frac{ 5 }{ 100 } =1539$$

x uchun yechish

$$x=1800$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{10}{100} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x-x\times \frac{1}{10}-\left(x-x\times \frac{10}{100}\right)\times \frac{5}{100}=1539$$

\frac{9}{10}x ni olish uchun x va -x\times \frac{1}{10} ni birlashtirish.

$$\frac{9}{10}x-\left(x-x\times \frac{10}{100}\right)\times \frac{5}{100}=1539$$

\frac{10}{100} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{9}{10}x-\left(x-x\times \frac{1}{10}\right)\times \frac{5}{100}=1539$$

\frac{9}{10}x ni olish uchun x va -x\times \frac{1}{10} ni birlashtirish.

$$\frac{9}{10}x-\frac{9}{10}x\times \frac{5}{100}=1539$$

\frac{5}{100} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{9}{10}x-\frac{9}{10}x\times \frac{1}{20}=1539$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{9}{10} ni \frac{1}{20} ga ko‘paytiring.

$$\frac{9}{10}x-\frac{9\times 1}{10\times 20}x=1539$$

\frac{9\times 1}{10\times 20} kasridagi ko‘paytirishlarni bajaring.

$$\frac{9}{10}x-\frac{9}{200}x=1539$$

\frac{171}{200}x ni olish uchun \frac{9}{10}x va -\frac{9}{200}x ni birlashtirish.

$$\frac{171}{200}x=1539$$

Ikki tarafini \frac{200}{171} va teskari kasri \frac{171}{200} ga ko‘paytiring.

$$x=1539\times \frac{200}{171}$$

1539\times \frac{200}{171} ni yagona kasrga aylantiring.

$$x=\frac{1539\times 200}{171}$$

307800 hosil qilish uchun 1539 va 200 ni ko'paytirish.

$$x=\frac{307800}{171}$$

1800 ni olish uchun 307800 ni 171 ga bo‘ling.

$$x=1800$$
