x+y+xy=16 eching

$$x+y+xy=16$$

x uchun yechish

$$x=-\frac{y-16}{y+1}$$

$$y\neq -1$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan y ni ayirish.

$$x+xy=16-y$$

x'ga ega bo'lgan barcha shartlarni birlashtirish.

$$\left(1+y\right)x=16-y$$

Tenglama standart shaklda.

$$\left(y+1\right)x=16-y$$

Ikki tarafini 1+y ga bo‘ling.

$$\frac{\left(y+1\right)x}{y+1}=\frac{16-y}{y+1}$$

1+y ga bo'lish 1+y ga ko'paytirishni bekor qiladi.

$$x=\frac{16-y}{y+1}$$

y uchun yechish

$$y=-\frac{x-16}{x+1}$$

$$x\neq -1$$
