5r-2t=10 eching

$$5 r - 2 t = 10$$

r uchun yechish

$$r=\frac{2\left(t+5\right)}{5}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

2t ni ikki tarafga qo’shing.

$$5r=10+2t$$

Tenglama standart shaklda.

$$5r=2t+10$$

Ikki tarafini 5 ga bo‘ling.

$$\frac{5r}{5}=\frac{2t+10}{5}$$

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

$$r=\frac{2t+10}{5}$$

10+2t ni 5 ga bo'lish.

$$r=\frac{2t}{5}+2$$

t uchun yechish

$$t=\frac{5\left(r-2\right)}{2}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan 5r ni ayirish.

$$-2t=10-5r$$

Ikki tarafini -2 ga bo‘ling.

$$\frac{-2t}{-2}=\frac{10-5r}{-2}$$

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

$$t=\frac{10-5r}{-2}$$

10-5r ni -2 ga bo'lish.

$$t=\frac{5r}{2}-5$$
