Freight train x 330 miles
\n" ); document.write( "Passenger train x+14 400 miles
\n" ); document.write( "
\n" ); document.write( "330/x=400/(x+14)
\n" ); document.write( "330/x-400(x+14)
\n" ); document.write( "LCD = x(x+14) =
\n" ); document.write( "Multiply by LCD
\n" ); document.write( "330(x+14)-400x= 0
\n" ); document.write( "330x+4620-400*x =0
\n" ); document.write( "-70x+4620=0
\n" ); document.write( "-70x=-4620
\n" ); document.write( "/-70
\n" ); document.write( "x=66 speed of Freight train
\n" ); document.write( "x+14=> 80 speed of Passenger train
\n" ); document.write( "
\n" ); document.write( "
\n" );
