You can put this solution on YOUR website!
let the digits be x & y x in the tens place and y in the units place\r
\n" ); document.write( "\n" ); document.write( "x+y=11\r
\n" ); document.write( "\n" ); document.write( "The number is 10x+y\r
\n" ); document.write( "\n" ); document.write( "reversed
\n" ); document.write( "10y+x\r
\n" ); document.write( "\n" ); document.write( "10y+x= 10x+y +45\r
\n" ); document.write( "\n" ); document.write( "9y-9x=45
\n" ); document.write( "/9
\n" ); document.write( "y-x=5\r
\n" ); document.write( "\n" ); document.write( "x+y =11
\n" ); document.write( "y-x=5\r
\n" ); document.write( "\n" ); document.write( "add the two equations
\n" ); document.write( "2y=16
\n" ); document.write( "/2
\n" ); document.write( "x=8
\n" ); document.write( "if x = 8 then y= 3\r
\n" ); document.write( "\n" ); document.write( "the number is 83\r
