Answer
$ x= \frac{5}{12}$
Work Step by Step
$\frac{7}{4} + \frac{1}{5}x - \frac{3}{2} = \frac{4}{5}x$
$\frac{7}{4} + \frac{1}{5}x - \frac{6}{4} - \frac{4}{5}x = 0$
$\frac{7-6}{4} + \frac{1-4}{5}x = 0$
$ \frac{-3}{5}x = -\frac{1}{4}$
$ \frac{-3}{5}x \times20= -\frac{1}{4}\times20$
$ -12x= -5$
$ x= \frac{5}{12}$
