\n" ); document.write( "s = j + 4
\n" ); document.write( "-----
\n" ); document.write( "s = (1/2)r
\n" ); document.write( "----
\n" ); document.write( "s + j + r = 60
\n" ); document.write( "----
\n" ); document.write( "Substitute for \"j\" and \"r\" to get:
\n" ); document.write( "s + s-4 + 2s = 60
\n" ); document.write( "4s = 64
\n" ); document.write( "s = 16
