4x/5+1/5+9=5x/6-7/5 eching

$$\frac { 4 x } { 5 } + \frac { 1 } { 5 } + 9 = \frac { 5 x } { 6 } - \frac { 7 } { 5 }$$

x uchun yechish

$$x=318$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 30 ga, 5,6 ning eng kichik karralisiga ko‘paytiring.

$$6\times 4x+6+270=5\times 5x-42$$

24 hosil qilish uchun 6 va 4 ni ko'paytirish.

$$24x+6+270=5\times 5x-42$$

276 olish uchun 6 va 270'ni qo'shing.

$$24x+276=5\times 5x-42$$

25 hosil qilish uchun 5 va 5 ni ko'paytirish.

$$24x+276=25x-42$$

Ikkala tarafdan 25x ni ayirish.

$$24x+276-25x=-42$$

-x ni olish uchun 24x va -25x ni birlashtirish.

$$-x+276=-42$$

Ikkala tarafdan 276 ni ayirish.

$$-x=-42-276$$

-318 olish uchun -42 dan 276 ni ayirish.

$$-x=-318$$

Ikkala tarafini -1 ga ko‘paytiring.

$$x=318$$
