4*f(x)=2x-1 eching

$$4 \cdot f ( x ) = 2 x - 1$$

f uchun yechish

$$f=\frac{1}{2}-\frac{1}{4x}$$

$$x\neq 0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglama standart shaklda.

$$4xf=2x-1$$

Ikki tarafini 4x ga bo‘ling.

$$\frac{4xf}{4x}=\frac{2x-1}{4x}$$

4x ga bo'lish 4x ga ko'paytirishni bekor qiladi.

$$f=\frac{2x-1}{4x}$$

2x-1 ni 4x ga bo'lish.

$$f=\frac{1}{2}-\frac{1}{4x}$$

x uchun yechish

$$x=-\frac{1}{2\left(2f-1\right)}$$

$$f\neq \frac{1}{2}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 2x ni ayirish.

$$4fx-2x=-1$$

x'ga ega bo'lgan barcha shartlarni birlashtirish.

$$\left(4f-2\right)x=-1$$

Ikki tarafini 4f-2 ga bo‘ling.

$$\frac{\left(4f-2\right)x}{4f-2}=-\frac{1}{4f-2}$$

4f-2 ga bo'lish 4f-2 ga ko'paytirishni bekor qiladi.

$$x=-\frac{1}{4f-2}$$

-1 ni 4f-2 ga bo'lish.

$$x=-\frac{1}{2\left(2f-1\right)}$$
