Question

8. Tenglamalarni yeching. a) 16 000 + 45 000 z = 19 000 b) 32 800: (1 800 - x) = 410​

Answer 1

Ma'lumotlarni topish uchun quyidagi tenglamalarni yechamiz:

a) 16,000 + 45,000z = 19,000

Avval, 16,000 ni 19,000 dan ayirib chiqaramiz:

19,000 - 16,000 = 3,000

Keyin, 45,000z ni 3,000 ga tenglashtiramiz:

45,000z = 3,000

Endi z ni topamiz, 45,000 ni 3,000 ga bo'lamiz:

z = 3,000 / 45,000

z = 1/15

Javob: z = 1/15

b) 32,800 ni (1,800 - x) ga bo'lib, natijani 410 ga tenglashtiramiz:

32,800 / (1,800 - x) = 410

Quyidagi o'zgaruvchini x ni topish uchun tenglama ichida ishlatamiz:

1,800 - x = 32,800 / 410

1,800 - x = 80

Endi x ni topamiz, 1,800 dan 80 ni ayirib chiqaramiz:

x = 1,800 - 80

x = 1,720

Javob: x = 1,720
