(34-x)4/7=2/5x eching

$$( 34 - x ) \frac { 4 } { 7 } = \frac { 2 } { 5 } x$$

x uchun yechish

$$x=20$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

34-x ga \frac{4}{7} ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$34\times \frac{4}{7}-x\times \frac{4}{7}=\frac{2}{5}x$$

34\times \frac{4}{7} ni yagona kasrga aylantiring.

$$\frac{34\times 4}{7}-x\times \frac{4}{7}=\frac{2}{5}x$$

136 hosil qilish uchun 34 va 4 ni ko'paytirish.

$$\frac{136}{7}-x\times \frac{4}{7}=\frac{2}{5}x$$

-\frac{4}{7} hosil qilish uchun -1 va \frac{4}{7} ni ko'paytirish.

$$\frac{136}{7}-\frac{4}{7}x=\frac{2}{5}x$$

Ikkala tarafdan \frac{2}{5}x ni ayirish.

$$\frac{136}{7}-\frac{4}{7}x-\frac{2}{5}x=0$$

-\frac{34}{35}x ni olish uchun -\frac{4}{7}x va -\frac{2}{5}x ni birlashtirish.

$$\frac{136}{7}-\frac{34}{35}x=0$$

Ikkala tarafdan \frac{136}{7} ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-\frac{34}{35}x=-\frac{136}{7}$$

Ikki tarafini -\frac{35}{34} va teskari kasri -\frac{34}{35} ga ko‘paytiring.

$$x=-\frac{136}{7}\left(-\frac{35}{34}\right)$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali -\frac{136}{7} ni -\frac{35}{34} ga ko‘paytiring.

$$x=\frac{-136\left(-35\right)}{7\times 34}$$

\frac{-136\left(-35\right)}{7\times 34} kasridagi ko‘paytirishlarni bajaring.

$$x=\frac{4760}{238}$$

20 ni olish uchun 4760 ni 238 ga bo‘ling.

$$x=20$$
