\n" ); document.write( "\n" ); document.write( "Let I be the number.
\n" ); document.write( "Let x be the tens digit and y the ones.\r
\n" ); document.write( "\n" ); document.write( "Then I = (10*x + y)
\n" ); document.write( "Also x + y = I - 45\r
\n" ); document.write( "\n" ); document.write( "So;\r
\n" ); document.write( "\n" ); document.write( "x + y = (10x + y) - 45
\n" ); document.write( "9x = 45
\n" ); document.write( "x=5.
\n" ); document.write( " \n" ); document.write( "
