You can put this solution on YOUR website!
I see nothing wrong with your work.
\n" ); document.write( "The conclusion should be written as:
\n" ); document.write( "\"x+=+44\"
\n" ); document.write( "To check your solution, substitute x = 44 into the original equation and solve for y.
\n" ); document.write( "\"y+=+5%28x-%287-x%29%29-9%28x%2B1%29\" Substitute x = 44
\n" ); document.write( "\"y+=+5%2844-%287-44%29%29-9%2844%2B1%29\"
\n" ); document.write( "\"y+=+5%2844-%28-37%29%29-9%2845%29\"
\n" ); document.write( "\"y+=+5%2881%29-405\"
\n" ); document.write( "\"y+=+405-405\"
\n" ); document.write( "\"y+=+0\" Your solution (x = 44) is correct!
\n" ); document.write( "
\n" );
