3.5(x+x+10)=455
\n" ); document.write( "3.5(2x+10)=455
\n" ); document.write( "7x+35=455
\n" ); document.write( "7x=455-35
\n" ); document.write( "7x=420
\n" ); document.write( "x=420/7
\n" ); document.write( "x=60 mph for the slower car.
\n" ); document.write( "60+10=70 mph for the faster car.
\n" ); document.write( "Proof:
\n" ); document.write( "3.5(60+70)=455
\n" ); document.write( "3.5*130=455
\n" ); document.write( "455=455
\n" ); document.write( "
