RT=D basic rule for uniform travel rates.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x time done at 55 mph, y time done at 75 mph.
\n" ); document.write( "\"x%2By=5\";\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "RT means distance.
\n" ); document.write( "\"highlight_green%2855x%2B75y=340%29\" and again, \"highlight_green%28x%2By=5%29\".
\n" ); document.write( "Simplify the distance sum equation: \"11x%2B15y=68\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Any method you want, solve this system:
\n" ); document.write( "\"highlight%28system%2811x%2B15y=68%2Cx%2By=5%29%29\".
