150*80%-x=20%x eching

$$150 \times 80 \% -x=20 \% x$$

x uchun yechish

$$x=100$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$150\times \frac{4}{5}-x=\frac{20}{100}x$$

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

$$\frac{150\times 4}{5}-x=\frac{20}{100}x$$

600 hosil qilish uchun 150 va 4 ni ko'paytirish.

$$\frac{600}{5}-x=\frac{20}{100}x$$

120 ni olish uchun 600 ni 5 ga bo‘ling.

$$120-x=\frac{20}{100}x$$

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

$$120-x=\frac{1}{5}x$$

Ikkala tarafdan \frac{1}{5}x ni ayirish.

$$120-x-\frac{1}{5}x=0$$

-\frac{6}{5}x ni olish uchun -x va -\frac{1}{5}x ni birlashtirish.

$$120-\frac{6}{5}x=0$$

Ikkala tarafdan 120 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$-\frac{6}{5}x=-120$$

Ikki tarafini -\frac{5}{6} va teskari kasri -\frac{6}{5} ga ko‘paytiring.

$$x=-120\left(-\frac{5}{6}\right)$$

-120\left(-\frac{5}{6}\right) ni yagona kasrga aylantiring.

$$x=\frac{-120\left(-5\right)}{6}$$

600 hosil qilish uchun -120 va -5 ni ko'paytirish.

$$x=\frac{600}{6}$$

100 ni olish uchun 600 ni 6 ga bo‘ling.

$$x=100$$
