x + y = 42
\n" ); document.write( "x + 2 = y (consecutive even)
\n" ); document.write( "Substitute the known value of y from the second equation into the first.
\n" ); document.write( "x + y = 42
\n" ); document.write( "x + (x+2) = 42
\n" ); document.write( "2x + 2 = 42
\n" ); document.write( "2x = 40
\n" ); document.write( "x = 20
\n" ); document.write( ".
\n" ); document.write( "If the first number is 20, then the second even consecutive number is 22.
\n" ); document.write( "20 + 22 = 42
\n" ); document.write( "
\n" );
