total number of stamp = x
\n" ); document.write( "stamps from Canada =1/2x
\n" ); document.write( "stamps from france =1/4x
\n" ); document.write( "stamps from mexico =1/8x\r
\n" ); document.write( "\n" ); document.write( "stamps from italy =1/16x\r
\n" ); document.write( "\n" ); document.write( "stamps from US=4\r
\n" ); document.write( "\n" ); document.write( "ie,\r
\n" ); document.write( "\n" ); document.write( "1/2x+1/4x+1/8x+1/16x+4 =x
\n" ); document.write( "(1/2+1/4+1/8+1/16)x +4=x
\n" ); document.write( "15/16x+4=x
\n" ); document.write( "15x/16 -x =-4
\n" ); document.write( "15x-16x/16 =-4
\n" ); document.write( "-x/16 =-4
\n" ); document.write( "x=(-4)*(-16)
\n" ); document.write( "x=64
\n" ); document.write( "total number of stamps =64
\n" ); document.write( "
\n" );
