4x+4(x+14)=480
\n" ); document.write( "8x+56=480
\n" ); document.write( "8x=480-56
\n" ); document.write( "8x=424
\n" ); document.write( "x=424/8
\n" ); document.write( "x=53 mph. for the slower car.
\n" ); document.write( "Proof:
\n" ); document.write( "4*53+4(53+14)=480
\n" ); document.write( "212+4*67=480
\n" ); document.write( "212+268=480
\n" ); document.write( "480=480
\n" ); document.write( "
