Do it like this one:
\n" ); document.write( "----------------------
\n" ); document.write( "The length of a rectangle is 10 cm longer than its width. The perimeter of the rectangle is 68 cm. What are the length and width of the rectangle?
\n" ); document.write( "-------
\n" ); document.write( "Perimeter = 2W + 2L = 68
\n" ); document.write( "W + L = 34
\n" ); document.write( "L = W + 10
\n" ); document.write( "Sub for L in the 1st eqn
\n" ); document.write( "W + (W+10) = 34
\n" ); document.write( "2W + 10 = 34
\n" ); document.write( "W = 12 cm
\n" ); document.write( "L = 22 cm
\n" ); document.write( "
\n" ); document.write( "
\n" );
