First Digit = x


\n" ); document.write( "Second Digit = y

\r
\n" ); document.write( "\n" ); document.write( "x+y=14

\r
\n" ); document.write( "\n" ); document.write( "x=2y-4 (This comes from the relationship explained.)

\r
\n" ); document.write( "\n" ); document.write( "Substitute the value of x, in terms of y, from the second equation into the first.

\r
\n" ); document.write( "\n" ); document.write( "2y-4+y=14 ---> 3y=18 (combined y's, added 4 to both sides.)---> y = 6 (divided both sides by 3.)


\n" ); document.write( "x+6=14 (subtract 6 from both sides.) x=8\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
