Chiziqli tenglamalarni yechish bo'yicha qadamlar

5ni ikki tarafidan bekor qilish.

$$10^{-2}\times \frac{20}{1000}\times 2=x\times \frac{98}{1000}$$

-2 daraja ko‘rsatkichini 10 ga hisoblang va \frac{1}{100} ni qiymatni oling.

$$\frac{1}{100}\times \frac{20}{1000}\times 2=x\times \frac{98}{1000}$$

\frac{20}{1000} ulushini 20 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{100}\times \frac{1}{50}\times 2=x\times \frac{98}{1000}$$

\frac{1}{5000} hosil qilish uchun \frac{1}{100} va \frac{1}{50} ni ko'paytirish.

$$\frac{1}{5000}\times 2=x\times \frac{98}{1000}$$

\frac{1}{2500} hosil qilish uchun \frac{1}{5000} va 2 ni ko'paytirish.

$$\frac{1}{2500}=x\times \frac{98}{1000}$$

\frac{98}{1000} ulushini 2 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{1}{2500}=x\times \frac{49}{500}$$

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$x\times \frac{49}{500}=\frac{1}{2500}$$

Ikki tarafini \frac{500}{49} va teskari kasri \frac{49}{500} ga ko‘paytiring.

$$x=\frac{1}{2500}\times \frac{500}{49}$$

\frac{1}{245} hosil qilish uchun \frac{1}{2500} va \frac{500}{49} ni ko'paytirish.

$$x=\frac{1}{245}$$
