Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 100 ga, 25,100 ning eng kichik karralisiga ko‘paytiring.

$$4p\times \frac{80}{100}=1400$$

\frac{80}{100} ulushini 20 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$4p\times \frac{4}{5}=1400$$

4\times \frac{4}{5} ni yagona kasrga aylantiring.

$$\frac{4\times 4}{5}p=1400$$

16 hosil qilish uchun 4 va 4 ni ko'paytirish.

$$\frac{16}{5}p=1400$$

Ikki tarafini \frac{5}{16} va teskari kasri \frac{16}{5} ga ko‘paytiring.

$$p=1400\times \frac{5}{16}$$

1400\times \frac{5}{16} ni yagona kasrga aylantiring.

$$p=\frac{1400\times 5}{16}$$

7000 hosil qilish uchun 1400 va 5 ni ko'paytirish.

$$p=\frac{7000}{16}$$

\frac{7000}{16} ulushini 8 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$p=\frac{875}{2}$$
