164=P[21/20*21/20-1] eching

$$164 = P [ \frac { 21 } { 20 } \times \frac { 21 } { 20 } - 1 ]$$

P uchun yechish

$$P=1600$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{21}{20} ni \frac{21}{20} ga ko‘paytiring.

$$164=P\left(\frac{21\times 21}{20\times 20}-1\right)$$

\frac{21\times 21}{20\times 20} kasridagi ko‘paytirishlarni bajaring.

$$164=P\left(\frac{441}{400}-1\right)$$

1 ni \frac{400}{400} kasrga o‘giring.

$$164=P\left(\frac{441}{400}-\frac{400}{400}\right)$$

\frac{441}{400} va \frac{400}{400} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$164=P\times \frac{441-400}{400}$$

41 olish uchun 441 dan 400 ni ayirish.

$$164=P\times \frac{41}{400}$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$P\times \frac{41}{400}=164$$

Ikki tarafini \frac{400}{41} va teskari kasri \frac{41}{400} ga ko‘paytiring.

$$P=164\times \frac{400}{41}$$

164\times \frac{400}{41} ni yagona kasrga aylantiring.

$$P=\frac{164\times 400}{41}$$

65600 hosil qilish uchun 164 va 400 ni ko'paytirish.

$$P=\frac{65600}{41}$$

1600 ni olish uchun 65600 ni 41 ga bo‘ling.

$$P=1600$$
