X+Y=80
\n" ); document.write( "X=3Y-7
\n" ); document.write( "(3Y-7)+Y=80
\n" ); document.write( "4Y=80+7
\n" ); document.write( "4Y=87
\n" ); document.write( "Y=87/4
\n" ); document.write( "Y=21.75 ANS FOR THE SMALLER NUMBER.
\n" ); document.write( "X+21.75=80
\n" ); document.write( "X=80-21.75
\n" ); document.write( "X=58.75 ANS. FOR THE LARGER NUMBER.
\n" ); document.write( "PROOF:
\n" ); document.write( "3*21.75-7+21.75=80
\n" ); document.write( "65.25+21.75=80
\n" ); document.write( "80=80
