Tìm x biết: x+4/3 . 7/4 = 5 - 7/6

\(\left( {x + \frac{4}{3}} \right).\frac{7}{4} = 5 - \frac{7}{6}\)

\(\left( {x + \frac{4}{3}} \right).\frac{7}{4} = \frac{{23}}{6}\)

\(x + \frac{4}{3} = \frac{{23}}{6}:\frac{7}{4}\)

\[x + \frac{4}{3} = \frac{{46}}{{21}}\]

\[x = \frac{{46}}{{21}} - \frac{4}{3}\]

\[x = \frac{6}{7}\]

Vậy \[x = \frac{6}{7}\].
