\(\left(\frac{14}{5}x-50\right)\div\frac{2}{3}=51\)
\(\Leftrightarrow\frac{14}{5}x-50=51\times\frac{2}{3}\)
\(\Leftrightarrow\frac{14}{5}x-50=34\)
\(\Leftrightarrow\frac{14}{5}x=34+50\)
\(\Leftrightarrow\frac{14}{5}x=84\)

\(\left(\frac{14}{5}.x-50\right):\frac{2}{3}=51\)
\(\frac{14}{5}.x-50=51.\frac{2}{3}\)
\(\frac{14}{5}.x-50=34\)
\(\frac{14}{5}.x=34+50\)
\(\frac{14}{5}.x=84\)
\(x=84:\frac{14}{5}\)
\(x=30\)
( 14/5 . x - 50 ) : 2/3 = 51
14/5 . x - 50 = 51 . 2/3
14/5 .x - 50 = 34
14/5.x = 34 + 50
14/5.x = 84
=> x = 30
