k=deltak+28 eching

$$k = \delta k+28$$

k uchun yechish

$$k=\frac{28}{1-\delta }$$

$$\delta \neq 1$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan \delta k ni ayirish.

$$k-\delta k=28$$

k'ga ega bo'lgan barcha shartlarni birlashtirish.

$$\left(1-\delta \right)k=28$$

Ikki tarafini -\delta +1 ga bo‘ling.

$$\frac{\left(1-\delta \right)k}{1-\delta }=\frac{28}{1-\delta }$$

-\delta +1 ga bo'lish -\delta +1 ga ko'paytirishni bekor qiladi.

$$k=\frac{28}{1-\delta }$$

δ uchun yechish

$$\delta =\frac{k-28}{k}$$

$$k\neq 0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$\delta k+28=k$$

Ikkala tarafdan 28 ni ayirish.

$$\delta k=k-28$$

Tenglama standart shaklda.

$$k\delta =k-28$$

Ikki tarafini k ga bo‘ling.

$$\frac{k\delta }{k}=\frac{k-28}{k}$$

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

$$\delta =\frac{k-28}{k}$$
