Tìm x , biết: c) 7/ 4 − ( x + 5/ 3 ) = − 12 /5 ;
Giải thích
c) \(\frac{7}{4} - \left( {x + \frac{5}{3}} \right) = \frac{{ - 12}}{5}\)
\(x + \frac{5}{3} = \frac{7}{4} - \frac{{ - 12}}{5}\)
\(x + \frac{5}{3} = \frac{{83}}{{20}}\)
\(x = \frac{{83}}{{20}} - \frac{5}{3}\)
\(x = \frac{{149}}{{60}}\)
Vậy \(x = \frac{{149}}{{60}}\).
