BA*B+3=57A eching

$$B A \cdot B + 3 = 57 A$$

A uchun yechish (complex solution)

$$A=-\frac{3}{B^{2}-57}$$

$$B\neq -\sqrt{57}\text{ and }B\neq \sqrt{57}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

B^{2} hosil qilish uchun B va B ni ko'paytirish.

$$B^{2}A+3=57A$$

Ikkala tarafdan 57A ni ayirish.

$$B^{2}A+3-57A=0$$

Ikkala tarafdan 3 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$B^{2}A-57A=-3$$

A'ga ega bo'lgan barcha shartlarni birlashtirish.

$$\left(B^{2}-57\right)A=-3$$

Ikki tarafini B^{2}-57 ga bo‘ling.

$$\frac{\left(B^{2}-57\right)A}{B^{2}-57}=-\frac{3}{B^{2}-57}$$

B^{2}-57 ga bo'lish B^{2}-57 ga ko'paytirishni bekor qiladi.

$$A=-\frac{3}{B^{2}-57}$$

A uchun yechish

$$A=-\frac{3}{B^{2}-57}$$

$$|B|\neq \sqrt{57}$$
