Answer:

Step-by-step explanation:

If the 2 numbers are x and y then

x - y = 10

xy = 11

From the second equation :

y = 11/x

So, substituting in first equation:

x - 11/x = 10

Multiply through by x:

x^2 - 11 = 10x

x^2 - 10x - 11 = 0

(x - 11)(x + 1) = 0

x = -1, 11.

Giving y = -11, 1

So the 2 numbers are either -1 and -11

or 1 and 11.
