You're getting the wrong answer because your INITIAL equation is incorrect.
\n" );
document.write( "86 = 2(7) + 2w <======= THIS IS WRONG
\n" );
document.write( "Let width be W
\n" );
document.write( "Then length is: 2W + 7
\n" );
document.write( "86 = 2(W) + 2(2W + 7) <========== This is what the equation should be \n" );
document.write( "
\n" );
