\n" ); document.write( "Let x = cost of he bike
\n" ); document.write( "then
\n" ); document.write( "(x - 73) = amt that B has
\n" ); document.write( "and
\n" ); document.write( "(x - 65) = amt that M has
\n" ); document.write( ":
\n" ); document.write( "A simple equation
\n" ); document.write( "(x-73) + (x-65) = x
