x for length
\n" ); document.write( "y for width\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x=3y;
\n" ); document.write( "If x+6 and y+5, (not sure if means by units or \"times\"), then x+6=2(y+5).\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "System of Equations:
\n" ); document.write( "\"x=3y\" and \"x%2B6=2%28y%2B5%29+\"
\n" ); document.write( "Simplify second equation,
\n" ); document.write( "\"x%2B6=2y%2B10\"
\n" ); document.write( "\"x-2y=4\".
\n" ); document.write( "Substitute using the x formula:
\n" ); document.write( "\"%283y%29-2y=4\"
\n" ); document.write( "\"highlight%28y=4%29\" meaning \"x=3%2Ay=3%2A4=highlight%2812%29\"
