2x-4y=3 eching

$$2 x - 4 y = 3$$

x uchun yechish

$$x=2y+\frac{3}{2}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

4y ni ikki tarafga qo’shing.

$$2x=3+4y$$

Tenglama standart shaklda.

$$2x=4y+3$$

Ikki tarafini 2 ga bo‘ling.

$$\frac{2x}{2}=\frac{4y+3}{2}$$

2 ga bo'lish 2 ga ko'paytirishni bekor qiladi.

$$x=\frac{4y+3}{2}$$

3+4y ni 2 ga bo'lish.

$$x=2y+\frac{3}{2}$$

y uchun yechish

$$y=\frac{x}{2}-\frac{3}{4}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 2x ni ayirish.

$$-4y=3-2x$$

Ikki tarafini -4 ga bo‘ling.

$$\frac{-4y}{-4}=\frac{3-2x}{-4}$$

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

$$y=\frac{3-2x}{-4}$$

3-2x ni -4 ga bo'lish.

$$y=\frac{x}{2}-\frac{3}{4}$$
