12T+5(5.5-T)=43.25
\n" ); document.write( "12T+27.5-5T=43.25
\n" ); document.write( "7T=43.25-27.5
\n" ); document.write( "7T=15.75
\n" ); document.write( "T=15.75/7
\n" ); document.write( "T=2.25 HOURS FOR THE CANOE TRIP.
\n" ); document.write( "5.5-2.25=3.25 HOURS FOR THE HIKE.
\n" ); document.write( "5*3.25=16.25 MILES WAS THE LENGTH OF THE HIKE.
\n" ); document.write( "PROOF
\n" ); document.write( "12*2.25+5*3.25=43.25
\n" ); document.write( "27+16.25=43.25
\n" ); document.write( "43.25=43.25
