x = length
\n" ); document.write( "y = width\r
\n" ); document.write( "\n" ); document.write( "\"x=-35%2B6y\"
\n" ); document.write( "and
\n" ); document.write( "area is \"xy=5379\"\r
\n" ); document.write( "\n" ); document.write( "Find x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Easiest is find y in terms of x and rewrite the area equation.
\n" ); document.write( "\"x=6y-35+\"
\n" ); document.write( "\"6y=x%2B35\"
\n" ); document.write( "\"y=%28x%2B35%29%2F6\", substitute this.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%28x%2B35%29%2F6=5379\" , the substitution made into the area equation.
\n" ); document.write( "\"x%5E2%2B35x=6%2A5379\"
\n" ); document.write( "\"highlight%28x%5E2%2B35x-6%2A5379=0%29\"
\n" ); document.write( "Use general solution to quadratic formula, use the positive sqrt,
\n" ); document.write( "\"highlight%28x=163%29\"
\n" ); document.write( "
\n" );
