S=3F
\n" ); document.write( "T=5F-2
\n" ); document.write( "F+S+T=115
\n" ); document.write( "F+3F+(5F-2)=115
\n" ); document.write( "9F=115+2
\n" ); document.write( "9F=117
\n" ); document.write( "F=117/9
\n" ); document.write( "F=13 FOR THE FIRST NUMBER.
\n" ); document.write( "3*13=39 FOR THE SECOND NUMBER.
\n" ); document.write( "5*13-2=65-2=63 FOR THE THIRD NUMBER.
\n" ); document.write( "PROOF:
