300*0n^2/2=78*3000*(430-x) eching

$$300 \times 0 n ^ { 2 } / 2 = 78 \times 3000 \times ( 430 - x )$$

x uchun yechish

$$x=430$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 2 ga ko'paytirish.

$$300\times 0n^{2}=156\times 3000\left(430-x\right)$$

0 hosil qilish uchun 300 va 0 ni ko'paytirish.

$$0n^{2}=156\times 3000\left(430-x\right)$$

Har qanday sonni nolga ko‘paytirsangiz, nol chiqadi.

$$0=156\times 3000\left(430-x\right)$$

468000 hosil qilish uchun 156 va 3000 ni ko'paytirish.

$$0=468000\left(430-x\right)$$

468000 ga 430-x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$0=201240000-468000x$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$201240000-468000x=0$$

Ikkala tarafdan 201240000 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-468000x=-201240000$$

Ikki tarafini -468000 ga bo‘ling.

$$x=\frac{-201240000}{-468000}$$

430 ni olish uchun -201240000 ni -468000 ga bo‘ling.

$$x=430$$

n uchun yechish (complex solution)

$$n\in \mathrm{C}$$

$$x=430$$

n uchun yechish

$$n\in \mathrm{R}$$

$$x=430$$
