35(2x-1)=7(x+4)+3x eching

$$35 ( 2 x - 1 ) = 7 ( x + 4 ) + 3 x$$

x uchun yechish

$$x = \frac{21}{20} = 1\frac{1}{20} = 1,05$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

35 ga 2x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$70x-35=7\left(x+4\right)+3x$$

7 ga x+4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$70x-35=7x+28+3x$$

10x ni olish uchun 7x va 3x ni birlashtirish.

$$70x-35=10x+28$$

Ikkala tarafdan 10x ni ayirish.

$$70x-35-10x=28$$

60x ni olish uchun 70x va -10x ni birlashtirish.

$$60x-35=28$$

35 ni ikki tarafga qo’shing.

$$60x=28+35$$

63 olish uchun 28 va 35'ni qo'shing.

$$60x=63$$

Ikki tarafini 60 ga bo‘ling.

$$x=\frac{63}{60}$$

\frac{63}{60} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x=\frac{21}{20}$$
