Two times an unknown number is at least 4, and 8 more than the number exceeds 5. Find all possible values for the unknown number.

Let n be the number.

>>Two times an unknown number is at least 4<<

2n ≥ 4 
 n ≥ 2

8 more than the number exceeds 5

n+8 > 5
  n > -3

So if n ≥ 2, it's certainly > -3, so any number 2 
or greater satisfies that.
