x-10/100x+20/100x-30/100x=756 eching

$$x - \frac { 10 } { 100 } x + \frac { 20 } { 100 } x - \frac { 30 } { 100 } x = 756$$

x uchun yechish

$$x=945$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{10}{100} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$x-\frac{1}{10}x+\frac{20}{100}x-\frac{30}{100}x=756$$

\frac{9}{10}x ni olish uchun x va -\frac{1}{10}x ni birlashtirish.

$$\frac{9}{10}x+\frac{20}{100}x-\frac{30}{100}x=756$$

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

$$\frac{9}{10}x+\frac{1}{5}x-\frac{30}{100}x=756$$

\frac{11}{10}x ni olish uchun \frac{9}{10}x va \frac{1}{5}x ni birlashtirish.

$$\frac{11}{10}x-\frac{30}{100}x=756$$

\frac{30}{100} ulushini 10 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{11}{10}x-\frac{3}{10}x=756$$

\frac{4}{5}x ni olish uchun \frac{11}{10}x va -\frac{3}{10}x ni birlashtirish.

$$\frac{4}{5}x=756$$

Ikki tarafini \frac{5}{4} va teskari kasri \frac{4}{5} ga ko‘paytiring.

$$x=756\times \frac{5}{4}$$

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

$$x=\frac{756\times 5}{4}$$

3780 hosil qilish uchun 756 va 5 ni ko'paytirish.

$$x=\frac{3780}{4}$$

945 ni olish uchun 3780 ni 4 ga bo‘ling.

$$x=945$$
