Tìm x , biết: m) − 12/15 ⋅ ( x − 1/2 ) = 5 /24 .

m) \(\frac{{ - 15}}{{12}} \cdot \left( {x - \frac{1}{2}} \right) = \frac{5}{{24}}\)

\(x - \frac{1}{2} = \frac{5}{{24}}:\frac{{ - 15}}{{12}}\)

\(x - \frac{1}{2} = \frac{5}{{24}} \cdot \frac{{12}}{{ - 15}}\)

\(x - \frac{1}{2} = \frac{{ - 1}}{6}\)

\(x = \frac{{ - 1}}{6} + \frac{1}{2}\)

\(x = \frac{{ - 1}}{6} + \frac{3}{6}\)

\(x = \frac{2}{6} = \frac{1}{3}.\)

Vậy \(x = \frac{1}{3}.\)
