2t+5n=65 eching

$$2 t + 5 n = 65$$

n uchun yechish

$$n=-\frac{2t}{5}+13$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 2t ni ayirish.

$$5n=65-2t$$

Ikki tarafini 5 ga bo‘ling.

$$\frac{5n}{5}=\frac{65-2t}{5}$$

5 ga bo'lish 5 ga ko'paytirishni bekor qiladi.

$$n=\frac{65-2t}{5}$$

65-2t ni 5 ga bo'lish.

$$n=-\frac{2t}{5}+13$$

t uchun yechish

$$t=\frac{65-5n}{2}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 5n ni ayirish.

$$2t=65-5n$$

Ikki tarafini 2 ga bo‘ling.

$$\frac{2t}{2}=\frac{65-5n}{2}$$

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

$$t=\frac{65-5n}{2}$$
