A survey of the daily commuting times, in minutes, of seven different Chicago-based employees at a certain company yielded a data set consisting of the values $31,13,44,32,53,22,$ and $44$. A survey of the daily commuting times, in minutes, of seven different San Francisco-based employees at the same company yielded a data set consisting of the values $46,31,19,33,48,x,$ and $38$. If the means of the two data sets are equal, what is the value of $x$?
