5*20*(1+02)2400/y+2400=3000 eching

$$5 \times 20 \times (1+02) \frac{ 2400 }{ y } +2400=3000$$

y uchun yechish

$$y=400$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

y qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini y ga ko'paytirish.

$$5\times 20\left(1+0\times 2\right)\times 2400+y\times 2400=3000y$$

100 hosil qilish uchun 5 va 20 ni ko'paytirish.

$$100\left(1+0\times 2\right)\times 2400+y\times 2400=3000y$$

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

$$100\left(1+0\right)\times 2400+y\times 2400=3000y$$

1 olish uchun 1 va 0'ni qo'shing.

$$100\times 1\times 2400+y\times 2400=3000y$$

100 hosil qilish uchun 100 va 1 ni ko'paytirish.

$$100\times 2400+y\times 2400=3000y$$

240000 hosil qilish uchun 100 va 2400 ni ko'paytirish.

$$240000+y\times 2400=3000y$$

Ikkala tarafdan 3000y ni ayirish.

$$240000+y\times 2400-3000y=0$$

-600y ni olish uchun y\times 2400 va -3000y ni birlashtirish.

$$240000-600y=0$$

Ikkala tarafdan 240000 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-600y=-240000$$

Ikki tarafini -600 ga bo‘ling.

$$y=\frac{-240000}{-600}$$

400 ni olish uchun -240000 ni -600 ga bo‘ling.

$$y=400$$
