Ta có: \(x< 8\frac{2}{3}-\frac{12}{5}< y\)
\(\Leftrightarrow x< \frac{26}{3}-\frac{12}{5}< y\)
\(\Leftrightarrow x< \frac{94}{15}< y\)
\(\Leftrightarrow x< 6,266...< y\)
\(\Rightarrow\hept{\begin{cases}x=6\\y=7\end{cases}}\)
Vậy x = 6, y = 7
\(x< 8\frac{2}{3}-\frac{12}{5}< y\)
\(x< \frac{26}{3}-\frac{12}{5}< y\)
\(x< \frac{26.5}{3.5}-\frac{12.3}{5.3}< y\)
\(x< \frac{130}{15}-\frac{36}{15}< y\)
\(x< \frac{94}{15}< y\)
\(x< 6,3< y\)
\(\Rightarrow x=6; y=7\)
