The setup ignores the perfect square statement and instead focuses on the relationship.
\n" ); document.write( "x+6=2x-4
\n" ); document.write( ".
\n" ); document.write( "Solving for 'x'
\n" ); document.write( ".
\n" ); document.write( "-x=-10
\n" ); document.write( "x = 10
\n" ); document.write( ".
\n" ); document.write( "Now we can check for the perfect square...
\n" ); document.write( ".
\n" ); document.write( "x+6 = 16 :: a perfect square
\n" ); document.write( ".
\n" ); document.write( "Continue checking for the other condition...
\n" ); document.write( "2x-4= 20-4 = 16, which =x+6
\n" ); document.write( "Correct!
\n" ); document.write( ".
\n" ); document.write( "Answer: The number is 10.
\n" ); document.write( ".
\n" ); document.write( "Done.
