The numbers are 14 & 16.

The equations you need to solve are:

x + y = 30

x - y = 2 ==> (redefine in terms of y) y = x - 2

substitute into first equation

x + x - 2 = 30

2x = 30 + 2

x = 32/2 = 16

16 + y = 30

30 - 16 = y = 14

x = 16

y = 14

And that's how that is done.

There is a much easier way. You know the numbers are two a part. So you do 30 ÷ 2 = 15. Then find one above and one below. Thats 14 and 16. Add them together and BOOM!!!! You get 30!
