x=((85+x)*32)div42 eching

$$x=((85+x) \times 32) \div 42$$

x uchun yechish

$$x=272$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

85+x ga 32 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$x=\frac{2720+32x}{42}$$

\frac{1360}{21}+\frac{16}{21}x natijani olish uchun 2720+32x ning har bir ifodasini 42 ga bo‘ling.

$$x=\frac{1360}{21}+\frac{16}{21}x$$

Ikkala tarafdan \frac{16}{21}x ni ayirish.

$$x-\frac{16}{21}x=\frac{1360}{21}$$

\frac{5}{21}x ni olish uchun x va -\frac{16}{21}x ni birlashtirish.

$$\frac{5}{21}x=\frac{1360}{21}$$

Ikki tarafini \frac{21}{5} va teskari kasri \frac{5}{21} ga ko‘paytiring.

$$x=\frac{1360}{21}\times \frac{21}{5}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1360}{21} ni \frac{21}{5} ga ko‘paytiring.

$$x=\frac{1360\times 21}{21\times 5}$$

Surat va maxrajdagi ikkala 21 ni qisqartiring.

$$x=\frac{1360}{5}$$

272 ni olish uchun 1360 ni 5 ga bo‘ling.

$$x=272$$
