X+Y=21 OR X=21-Y
\n" ); document.write( "3Y=4X
\n" ); document.write( "3Y=4(21-Y)
\n" ); document.write( "3Y=84-4Y
\n" ); document.write( "3Y+4Y=84
\n" ); document.write( "7Y=84
\n" ); document.write( "Y=84/7
\n" ); document.write( "Y=12 THE LARGER NUMBER.
\n" ); document.write( "X+12=21
\n" ); document.write( "X=21-12
\n" ); document.write( "X=9 THE SMALLER NUMBER.
