Tìm x, biết:

\(\Large \dfrac{7}{5} - x = \dfrac{3}{10}\)

Vậy x = ...

• A. \(\Large \dfrac{9}{10}\)
• B. \(\Large \dfrac{10}{10}\)
• C. \(\Large \dfrac{11}{10}\)
• D. \(\Large \dfrac{12}{10}\)

\(\Large \dfrac{7}{5} - x = \dfrac{3}{10}\)

\(\Large  x =\dfrac{7}{5} - \dfrac{3}{10}\)

\(\Large  x =\dfrac{14}{10} - \dfrac{3}{10}\)

\(\Large  x =\dfrac{11}{10}\)
