Question 891489
the product of two 2 digits numbers is 2117. the product of their units digit
is 27 and that of tens digit is 14. find the numbers
<pre>
The only two possible units digits that have product 27 are 9 and 3
The only two possible tens digits that have product 14 are 7 and 2

Therefore there are only two feasible answers 

23 and 79   or   29 and 73

23 and 79 have product 1817, so that's not it.
29 and 73 have product 2117, so that's it.

[You can't solve it with algebra because there are four unknowns but
only 3 statements from which to get an equation.]
