Baholash

$$\frac{2x}{5}+\frac{3y}{10}$$

Yechim qadamlari

0 hosil qilish uchun 0 va 2 ni ko'paytirish.

$$0x+\frac{4}{5}y-\left(-\frac{2}{5}x\right)+\frac{1}{10}y+\frac{7}{5}y-2y$$

Har qanday sonni nolga ko‘paytirsangiz, nol chiqadi.

$$0+\frac{4}{5}y-\left(-\frac{2}{5}x\right)+\frac{1}{10}y+\frac{7}{5}y-2y$$

Har qanday songa nolni qo‘shsangiz, o‘zi chiqadi.

$$\frac{4}{5}y-\left(-\frac{2}{5}x\right)+\frac{1}{10}y+\frac{7}{5}y-2y$$

-\frac{2}{5}x ning teskarisi \frac{2}{5}x ga teng.

$$\frac{4}{5}y+\frac{2}{5}x+\frac{1}{10}y+\frac{7}{5}y-2y$$

\frac{9}{10}y ni olish uchun \frac{4}{5}y va \frac{1}{10}y ni birlashtirish.

$$\frac{9}{10}y+\frac{2}{5}x+\frac{7}{5}y-2y$$

\frac{23}{10}y ni olish uchun \frac{9}{10}y va \frac{7}{5}y ni birlashtirish.

$$\frac{23}{10}y+\frac{2}{5}x-2y$$

\frac{3}{10}y ni olish uchun \frac{23}{10}y va -2y ni birlashtirish.

$$\frac{3}{10}y+\frac{2}{5}x$$

Omil

$$\frac{4x+3y}{10}$$

Yechim qadamlari

\frac{1}{10} omili.

$$\frac{0+8y+4x+y+14y-20y}{10}$$

Hisoblang: 8y+4x+y+14y-20y. Oʻxshash shartlarni koʻpaytirish va birlashtirish.
