\n" ); document.write( "X DATA:
\n" ); document.write( "time = 9/2 hrs/job ; rate = 2/9 job/hrs
\n" ); document.write( "--------------------------
\n" ); document.write( "y DATA:
\n" ); document.write( "time = 6 hrs/job ; rate = 1/6 job/hr
\n" ); document.write( "--------------------------
\n" ); document.write( "Together DATA:
\n" ); document.write( "time = x hrs/job ; rate = 1/x job/hr
\n" ); document.write( "------------------
\n" ); document.write( "Equation:
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "2/9 + 1/6 = 1/x
\n" ); document.write( "---
\n" ); document.write( "Multiply thru by 18x to get:
\n" ); document.write( "4x + 3x = 18
\n" ); document.write( "7x = 18
\n" ); document.write( "x = 2 4/7 hrs (time to do the job together)
