\(\frac{1}{3}-\left(\frac{2}{3}-x+\frac{5}{4}\right)=\frac{7}{12}-\left(\frac{5}{2}-\frac{13}{6}\right)\)
\(\frac{1}{3}-\left(\frac{2}{3}-x+\frac{5}{4}\right)=\frac{7}{12}-\frac{1}{3}\)
\(\frac{1}{3}-\left(\frac{2}{3}-x+\frac{5}{4}\right)=\frac{1}{4}\)
\(\frac{2}{3}-x+\frac{5}{4}=\frac{1}{3}-\frac{1}{4}\)
\(\frac{2}{3}-x+\frac{5}{4}=\frac{1}{12}\)
\(\frac{2}{3}-x=\frac{1}{12}-\frac{5}{4}\)
\(\frac{2}{3}-x=-\frac{7}{6}\)
\(x=\frac{2}{3}-\left(-\frac{7}{6}\right)\)
\(x=\frac{2}{3}+\frac{7}{6}\)
\(x=\frac{11}{6}\)
\(3\frac{1}{3}\div2\frac{2}{5}-1< x< 7\frac{2}{3}\cdot\frac{3}{7}+\frac{5}{7}\)
\(\frac{25}{18}-1< x< \frac{23}{7}+\frac{5}{7}\)
\(\frac{7}{18}< x< \frac{28}{7}\)
\(\frac{49}{126}< x< \frac{504}{126}\)
\(\Rightarrow x=\left(\frac{50}{126};\frac{51}{126};\frac{52}{126};......;\frac{503}{126}\right)\)
\(-\frac{13}{3}\cdot\left(\frac{1}{2}-\frac{1}{6}\right)< x< -\frac{2}{3}\cdot\left(\frac{1}{3}-\frac{1}{2}-\frac{3}{4}\right)\)
\(\Leftrightarrow-\frac{13}{3}\cdot\left(\frac{3}{6}-\frac{1}{6}\right)< x< -\frac{2}{3}\cdot\left(\frac{4}{12}-\frac{6}{12}-\frac{9}{12}\right)\)
\(\Leftrightarrow-\frac{13}{3}\cdot\frac{1}{3}< x< -\frac{2}{3}\cdot\left(-\frac{11}{12}\right)\)
\(\Leftrightarrow-\frac{13}{9}< x< \frac{11}{18}\)
\(\Leftrightarrow-\frac{26}{18}< x< \frac{11}{18}\)
\(\Leftrightarrow x\in\left\{-25;-24;-23;...;8;9;10\right\}\)
Vậy ...
