30x+6y=4 eching

$$30 x + 6 y = 4$$

x uchun yechish

$$x=-\frac{y}{5}+\frac{2}{15}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 6y ni ayirish.

$$30x=4-6y$$

Ikki tarafini 30 ga bo‘ling.

$$\frac{30x}{30}=\frac{4-6y}{30}$$

30 ga bo'lish 30 ga ko'paytirishni bekor qiladi.

$$x=\frac{4-6y}{30}$$

4-6y ni 30 ga bo'lish.

$$x=-\frac{y}{5}+\frac{2}{15}$$

y uchun yechish

$$y=\frac{2}{3}-5x$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 30x ni ayirish.

$$6y=4-30x$$

Ikki tarafini 6 ga bo‘ling.

$$\frac{6y}{6}=\frac{4-30x}{6}$$

6 ga bo'lish 6 ga ko'paytirishni bekor qiladi.

$$y=\frac{4-30x}{6}$$

4-30x ni 6 ga bo'lish.

$$y=\frac{2}{3}-5x$$
