[tex] \frac{2x}{8} = x + \frac{4}{20} \\ \\ \frac{x}{4} = x + \frac{4}{20} \\ \\ \frac{x}{4} = x + \frac{1}{5} \\ \\ x = 4x + \frac{4}{5} \\ \\ x - 4x = \frac{4}{5} \\ \\ -3x = \frac{4}{5} \\ \\ x = \frac{4}{5 \times -3} \\ \\ x = - \frac{4}{15} \\ \\ [/tex]
The final result is: x = - 4/15 or x = -0.2667.
