X IS THE FIRST NUMBER
\n" ); document.write( "7X IS THE SECOND NUMBER
\n" ); document.write( "X=X+100 IS THE THIRD NUMBER
\n" ); document.write( "X+7X+X+100=793
\n" ); document.write( "9X=793-100
\n" ); document.write( "9X=693
\n" ); document.write( "X=693/9
\n" ); document.write( "X=77 ANS
\n" ); document.write( "7*77=539 ANS.
\n" ); document.write( "77+100=177 ANS.
\n" ); document.write( "PROOF:
\n" ); document.write( "77+539+177=793
\n" ); document.write( "793=793
