Just rely on uniform rates concept RT=J variables for rate, time, job. Your two agents work at rates of
\n" ); document.write( "a, \"1%2Fx\"
\n" ); document.write( "b, \"1%2F%28x%2B16%29\"
\n" ); document.write( "Combined rate \"1%2F15\"
\n" ); document.write( "Unit for the rate being \"Pieces of work per day\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The rates for both a and b working together are just combined with addition.
\n" ); document.write( "\"highlight%281%2Fx%2B1%2F%28x%2B16%29=1%2F15%29\"
\n" ); document.write( "so solve for x using this equation.
