4/9+(x-1/2)=3 eching

$$\frac { 4 } { 9 } + ( x - \frac { 1 } { 2 } ) = 3$$

x uchun yechish

$$x = \frac{55}{18} = 3\frac{1}{18} \approx 3,055555556$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

9 va 2 ning eng kichik umumiy karralisi 18 ga teng. \frac{4}{9} va \frac{1}{2} ni 18 maxraj bilan kasrlarga aylantirib oling.

$$\frac{8}{18}+x-\frac{9}{18}=3$$

\frac{8}{18} va \frac{9}{18} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{8-9}{18}+x=3$$

-1 olish uchun 8 dan 9 ni ayirish.

$$-\frac{1}{18}+x=3$$

\frac{1}{18} ni ikki tarafga qo’shing.

$$x=3+\frac{1}{18}$$

3 ni \frac{54}{18} kasrga o‘giring.

$$x=\frac{54}{18}+\frac{1}{18}$$

\frac{54}{18} va \frac{1}{18} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$x=\frac{54+1}{18}$$

55 olish uchun 54 va 1'ni qo'shing.

$$x=\frac{55}{18}$$
