Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{15}{100} ulushini 5 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x+\frac{3}{20}+\frac{20}{100}=7452$$

\frac{20}{100} ulushini 20 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x+\frac{3}{20}+\frac{1}{5}=7452$$

20 va 5 ning eng kichik umumiy karralisi 20 ga teng. \frac{3}{20} va \frac{1}{5} ni 20 maxraj bilan kasrlarga aylantirib oling.

$$x+\frac{3}{20}+\frac{4}{20}=7452$$

\frac{3}{20} va \frac{4}{20} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$x+\frac{3+4}{20}=7452$$

7 olish uchun 3 va 4'ni qo'shing.

$$x+\frac{7}{20}=7452$$

Ikkala tarafdan \frac{7}{20} ni ayirish.

$$x=7452-\frac{7}{20}$$

7452 ni \frac{149040}{20} kasrga o‘giring.

$$x=\frac{149040}{20}-\frac{7}{20}$$

\frac{149040}{20} va \frac{7}{20} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$x=\frac{149040-7}{20}$$

149033 olish uchun 149040 dan 7 ni ayirish.

$$x=\frac{149033}{20}$$
