Step-by-step explanation:
Hello,
Let's note a and b the two numbers.
a = b - 5
We replace a in the second equation and we solve it
It means that the sum of the two roots is 5 and the product is -66.
because
And we can notice that 66 = 6 * 11 and 11 - 6 = 5
So let's factorise it !
It means that the solutions are
(6,11) and (-6,-11)
I guess we are after positive numbers though.
Hope this helps.
