y+3/4geq1/5 eching

$$y + \frac { 3 } { 4 } \geq \frac { 1 } { 5 }$$

y uchun yechish

$$y\geq -\frac{11}{20}$$

Yechim qadamlari

Ikkala tarafdan \frac{3}{4} ni ayirish.

$$y\geq \frac{1}{5}-\frac{3}{4}$$

5 va 4 ning eng kichik umumiy karralisi 20 ga teng. \frac{1}{5} va \frac{3}{4} ni 20 maxraj bilan kasrlarga aylantirib oling.

$$y\geq \frac{4}{20}-\frac{15}{20}$$

\frac{4}{20} va \frac{15}{20} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$y\geq \frac{4-15}{20}$$

-11 olish uchun 4 dan 15 ni ayirish.

$$y\geq -\frac{11}{20}$$
