second=3f
\n" ); document.write( "third=s-5
\n" ); document.write( "f=first
\n" ); document.write( "f+3f+(3f-5)=254
\n" ); document.write( "7f-5=254
\n" ); document.write( "7f=254+5
\n" ); document.write( "7f=259
\n" ); document.write( "f=259/7
\n" ); document.write( "f=37 is the first number.
\n" ); document.write( "s=3*37=111 is the second number.
\n" ); document.write( "t=111-5=106 is the third number.
\n" ); document.write( "Proof:
\n" ); document.write( "37+111+106=254
\n" ); document.write( "254=254
