the product of two 2 digits numbers is 2117. the product of their units digit
\n" ); document.write( "is 27 and that of tens digit is 14. find the numbers
\n" ); document.write( "

\r\n" );
document.write( "The only two possible units digits that have product 27 are 9 and 3\r\n" );
document.write( "The only two possible tens digits that have product 14 are 7 and 2\r\n" );
document.write( "\r\n" );
document.write( "Therefore there are only two feasible answers \r\n" );
document.write( "\r\n" );
document.write( "23 and 79   or   29 and 73\r\n" );
document.write( "\r\n" );
document.write( "23 and 79 have product 1817, so that's not it.\r\n" );
document.write( "29 and 73 have product 2117, so that's it.\r\n" );
document.write( "\r\n" );
document.write( "[You can't solve it with algebra because there are four unknowns but\r\n" );
document.write( "only 3 statements from which to get an equation.]\r\n" );
