1/30+1/x=1/20 eching

$$\frac{ 1 }{ 30 } + \frac{ 1 }{ x } = \frac{ 1 }{ 20 }$$

x uchun yechish

$$x=60$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

x qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 60x ga, 30,x,20 ning eng kichik karralisiga ko‘paytiring.

$$60x\times \frac{1}{30}+60=3x$$

\frac{60}{30} hosil qilish uchun 60 va \frac{1}{30} ni ko'paytirish.

$$\frac{60}{30}x+60=3x$$

2 ni olish uchun 60 ni 30 ga bo‘ling.

$$2x+60=3x$$

Ikkala tarafdan 3x ni ayirish.

$$2x+60-3x=0$$

-x ni olish uchun 2x va -3x ni birlashtirish.

$$-x+60=0$$

Ikkala tarafdan 60 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-x=-60$$

Ikkala tarafini -1 ga ko‘paytiring.

$$x=60$$
