There are 3 numbers: x, y, z.
\n" ); document.write( "x+y+z=99
\n" ); document.write( "y = x-10
\n" ); document.write( "z = x-20
\n" ); document.write( ".
\n" ); document.write( "x + x-10 +x-20 = 99
\n" ); document.write( "3x -30 = 99
\n" ); document.write( "3x = 129
\n" ); document.write( "x = 43
\n" ); document.write( "y = 33
\n" ); document.write( "z = 23
\n" ); document.write( ".
\n" ); document.write( "x + y + z = 43 +33 + 23
\n" ); document.write( "43 + 33 + 23 = 99
\n" ); document.write( "Check.
\n" ); document.write( ".
\n" ); document.write( "The greatest of the three numbers is 43.
\n" ); document.write( ".
