y-2/5=3/4 eching

$$y - \frac { 2 } { 5 } = \frac { 3 } { 4 }$$

y uchun yechish

$$y = \frac{23}{20} = 1\frac{3}{20} = 1,15$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{2}{5} ni ikki tarafga qo’shing.

$$y=\frac{3}{4}+\frac{2}{5}$$

4 va 5 ning eng kichik umumiy karralisi 20 ga teng. \frac{3}{4} va \frac{2}{5} ni 20 maxraj bilan kasrlarga aylantirib oling.

$$y=\frac{15}{20}+\frac{8}{20}$$

\frac{15}{20} va \frac{8}{20} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$y=\frac{15+8}{20}$$

23 olish uchun 15 va 8'ni qo'shing.

$$y=\frac{23}{20}$$
