Answer 2

Let the 2 numbers be x and y.

$\bold{Given}$

Sum of 2 numbers = 18

$=> x + y = 18$

Difference of 2 numbers = 2

$=> x - y = 2$

Solving, we get,

$x + y = 18\\x-y=2\\\boxed{\boxed{x = 10}}$

Substituting, in the first eq. , we get,

$10 + y = 18\\=> \boxed{\boxed{y = 8}}$

$\boxed {\boxed{\underline {\bold{Therefore, \ the \ 2 \ numbers \ are \ 10 \ and \ 8.}}}}$
