A printing machine prints 1000 pages in 15 minutes. A second machine is required so that, together, they print 1000 pages in only 5 minutes. Determine the equation used to find the time $x$ (in minutes) for the second machine to print 1000 pages alone.
A) $\frac{1}{15} + \frac{x}{5} = 1$
B) $\frac{1}{15} + \frac{1}{x} = \frac{1}{5}$
C) $\frac{15}{1000} + \frac{x}{1000} = 1$
D) $15-x = 5$
E) None of these
