4x+2y=5 eching

$$4 x + 2 y = 5$$

x uchun yechish

$$x=-\frac{y}{2}+\frac{5}{4}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 2y ni ayirish.

$$4x=5-2y$$

Ikki tarafini 4 ga bo‘ling.

$$\frac{4x}{4}=\frac{5-2y}{4}$$

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

$$x=\frac{5-2y}{4}$$

5-2y ni 4 ga bo'lish.

$$x=-\frac{y}{2}+\frac{5}{4}$$

y uchun yechish

$$y=\frac{5}{2}-2x$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 4x ni ayirish.

$$2y=5-4x$$

Ikki tarafini 2 ga bo‘ling.

$$\frac{2y}{2}=\frac{5-4x}{2}$$

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

$$y=\frac{5-4x}{2}$$

5-4x ni 2 ga bo'lish.

$$y=\frac{5}{2}-2x$$
