let units digit be x
\n" ); document.write( "and tens digit be y\r
\n" ); document.write( "\n" ); document.write( "x+y+3 = 2x
\n" ); document.write( "x-y=3........(1)\r
\n" ); document.write( "\n" ); document.write( "(10y+x)= (x+y) *4 +3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "subtract the equations\r
\n" ); document.write( "\n" ); document.write( "6y-3x =3
\n" ); document.write( "2y-x=1........(2)\r
\n" ); document.write( "\n" ); document.write( "add 1 & 2
\n" ); document.write( "y=4
\n" ); document.write( "therefore x=7\r
\n" ); document.write( "\n" ); document.write( "Number is 47\r
\n" ); document.write( "\n" ); document.write( "
