Larry worked for 3 hours at the rate of 1/8 per hour.
\n" ); document.write( "No need for two equations.
\n" ); document.write( "Larry already did 3/8 of the job
\n" ); document.write( "Pat and Larry will work together for 2 hours, Larry at 1/8 for each hour and Pat at x per hour for 2 hours\r
\n" ); document.write( "\n" ); document.write( "3/8+2/8+2/x=1
\n" ); document.write( "5/8=2/x=1
\n" ); document.write( "2/x=3/8
\n" ); document.write( "16=3x
\n" ); document.write( "16/3=x
\n" ); document.write( "5 1/3=x
\n" ); document.write( "So Pat would do the whole house alone in 5 1/3 hours.
\n" ); document.write( "Larry had already done 3/8 with pat he did 2/8. So Larry did 5/8 and Pat did 3/8
\n" ); document.write( "of the total job.\r
\n" ); document.write( "\n" ); document.write( "Larry worked 5 hours total.
\n" ); document.write( "5/8+3/8=1\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
