Let the number be xy
\n" ); document.write( "x in the tens place and y in units place\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1 x + 1 y = 13 .............1
\n" ); document.write( "-9 x + 9 y = 27 .............2
\n" ); document.write( "9 y
\n" ); document.write( "multiply (1)by 9
\n" ); document.write( "Multiply (2) by -1
\n" ); document.write( "9 x 9 y = 117
\n" ); document.write( "9 x + -9 y = -27
\n" ); document.write( "Add the two equations
\n" ); document.write( "18 x = 90.000
\n" ); document.write( "/ 18
\n" ); document.write( "x = 5
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 1 y = 13
\n" ); document.write( "5 + 1 y = 13
\n" ); document.write( " 1 y = 13-5
\n" ); document.write( " 1 y = 8
\n" ); document.write( " y = 8
\n" ); document.write( "
\n" ); document.write( "
\n" );
