Step 1. Given Information.

The equation is $\frac{7}{10} x - \frac{1}{5} = \frac{3}{8}$ .

Step 2. Calculation.

First, find out the LCD and then the LCD has to substitute each side.

$\begin{matrix} \frac{7}{10} x - \frac{1}{5} = \frac{3}{8} \\ 40 (\frac{7}{10} x - \frac{1}{5}) = 40 (\frac{3}{8}) \\ 40 (\frac{7}{10} x) - 40 (\frac{1}{5}) = 40 (\frac{3}{8}) \\ 28 x - 8 = 15 \end{matrix}$

On further simplification,

$\begin{matrix} 28 x = 15 + 8 \\ 28 x = 23 \\ x = \frac{23}{28} \end{matrix}$

Step 3. Conclusion.

The solution of the given equation is $x = \frac{23}{28}$ .
