1/5+7/10=18/x+36/x eching

$$\frac { 1 } { 5 } + \frac { 7 } { 10 } = 18 / x + 36 / x$$

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 10x ga, 5,10,x ning eng kichik karralisiga ko‘paytiring.

$$10x\times \frac{1}{5}+10x\times \frac{7}{10}=10\times 18+10\times 36$$

\frac{10}{5} hosil qilish uchun 10 va \frac{1}{5} ni ko'paytirish.

$$\frac{10}{5}x+10x\times \frac{7}{10}=10\times 18+10\times 36$$

2 ni olish uchun 10 ni 5 ga bo‘ling.

$$2x+10x\times \frac{7}{10}=10\times 18+10\times 36$$

10 va 10 ni qisqartiring.

$$2x+7x=10\times 18+10\times 36$$

9x ni olish uchun 2x va 7x ni birlashtirish.

$$9x=10\times 18+10\times 36$$

180 hosil qilish uchun 10 va 18 ni ko'paytirish. 360 hosil qilish uchun 10 va 36 ni ko'paytirish.

$$9x=180+360$$

540 olish uchun 180 va 360'ni qo'shing.

$$9x=540$$

Ikki tarafini 9 ga bo‘ling.

$$x=\frac{540}{9}$$

60 ni olish uchun 540 ni 9 ga bo‘ling.

$$x=60$$
