\n" ); document.write( "

Let time Melissa drove be T
\n" );
document.write( "Then time Kyle drove = 21 – T
\n" );
document.write( "We then get: 34T = 50(21 – T)
\n" );
document.write( "34T = 1,050 – 50T
\n" );
document.write( "34T + 50T = 1,050 
\n" );
document.write( "84T = 1,050
\n" );
document.write( "T, or time Melissa drove = , or  hours
\n" );
document.write( "Therefore, Kyle drove: 21 – 12.5, or  hours \n" );
