Answers: {4, 5}
========================================================
Explanation:
We have some number n and we're adding 1 to it to get n+1.
This n+1 is larger than 4. We want to find which values make n+1 > 4 true.
To find out, undo the operation "add 1" by subtracting 1 from both sides
n+1 > 4
n+1-1 > 4-1
n+0 > 3
n > 3
Anything larger than 3 will work. So that means {4,5} is the solution set from the original list of values.
For instance, if we tried n = 5, then
n+1 > 4
5+1 > 4 ... replace n with 5
6 > 4 ... true statement
But if we tried n = 1, then,
n+1 > 4
1+1 > 4
2 > 4 ... false; this shows n = 1 isn't in the solution set.
