35000=A*250-[15000+(A*150)] eching

$$35000 = A \times 250 - [ 15000 + ( A \times 150 ) ]$$

A uchun yechish

$$A=500$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

15000+A\times 150 teskarisini topish uchun har birining teskarisini toping.

$$35000=A\times 250-15000-A\times 150$$

-150 hosil qilish uchun -1 va 150 ni ko'paytirish.

$$35000=A\times 250-15000-150A$$

100A ni olish uchun A\times 250 va -150A ni birlashtirish.

$$35000=100A-15000$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$100A-15000=35000$$

15000 ni ikki tarafga qo’shing.

$$100A=35000+15000$$

50000 olish uchun 35000 va 15000'ni qo'shing.

$$100A=50000$$

Ikki tarafini 100 ga bo‘ling.

$$A=\frac{50000}{100}$$

500 ni olish uchun 50000 ni 100 ga bo‘ling.

$$A=500$$
