$$\frac{x+4}{2013} + \frac{x+5}{2015} - 62 = \frac{x+2003}{13} + \frac{x}{16} + 63$$$$\frac{x}{2013} + \frac{4}{2013} + \frac{x}{2015} + \frac{5}{2015} - 62 = \frac{x}{13} + \frac{2003}{13} + \frac{x}{16} + 63$$ $$x \left( \frac{1}{2013} + \frac{1}{2015} - \frac{1}{13} - \frac{1}{16} \right) = 63 + 62 + \frac{2003}{13} - \frac{4}{2013} - \frac{5}{2015}$$$$x = \frac{63 + 62 + \frac{2003}{13} - \frac{4}{2013} - \frac{5}{2015}}{\frac{1}{2013} + \frac{1}{2015} - \frac{1}{13} - \frac{1}{16}}$$$$x \approx -2015,982071$$
