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}$
