number 6 is written at end of a two digit number.value of number is increased by 600.
\n" ); document.write( "find two digit number.
\n" ); document.write( ":
\n" ); document.write( "(100x + 10y + 6) - (10x + y) = 600
\n" ); document.write( "100x - 10x + 10y - y + 6 = 600
\n" ); document.write( "90x + 9y = 600 - 6
\n" ); document.write( "90x + 9y = 594
\n" ); document.write( "Simplify, divide by 9
\n" ); document.write( "10x + y = 66
\n" ); document.write( "y = -10x + 66
\n" ); document.write( "we assume both x and y are positive single digit integers
\n" ); document.write( "only x=6 which makes y=6 satisfies this requirement
\n" ); document.write( ":
\n" ); document.write( "66 is the two digit number
\n" ); document.write( ":
\n" ); document.write( "666 - 66 = 600\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
