x = one number
\n" ); document.write( "y = another number
\n" ); document.write( "x + y = 45 :: given
\n" ); document.write( "x = y + 9 :: y is 9 less than x
\n" ); document.write( ".
\n" ); document.write( "substitute x = y+9 in the first equation
\n" ); document.write( ".
\n" ); document.write( "y+9 + y = 45
\n" ); document.write( "2y = 36
\n" ); document.write( "y = 18
\n" ); document.write( ".
\n" ); document.write( "now substitute y=18 in the second equation
\n" ); document.write( "x + y = 45
\n" ); document.write( "x + 18 = 45
\n" ); document.write( "x = 27
\n" ); document.write( ".
\n" ); document.write( "checking...
\n" ); document.write( "Is the smaller number 9 less than the larger number?
\n" ); document.write( "Yes.
