Question 922659
very clear you have 2 unknown numbers but you know their sum which is 12
so: let x= first number
        y= second number
        if you add them as the problem states:
        x+y=12 >>> eqn 1
then another condition is, their proudct is 27, meaning if you multiply them
the result is 27, therefore:
        x*y=27 or xy=27 or x=27/y >> eqn 2
substitube eqn 2 in eqn 1
        x+y=12
        (27/y)+y=12
        y=3 and y=9
        x=9 and y=3
 the two numbers are 9 & 3
