No
Step-by-step explanation:
Let's check the first statement with an example. 2 and 3 are positive numbers and their sum (5) is also positive so his first statement is true.
To check the second statement let's look at the negative numbers -1 and -8 for example. Their sum (-9) is also negative so his second statement is true.
To check the third statement let's look at the numbers 9 and -5. One is positive and one is negative, but their sum (4) is positive, so his third statement is false. However if we look at the numbers 4 and -7, their sum is negative so the third statement is partially false.

Answer:
20 and 13
Step-by-step explanation:
If one list is 'a' and the other one is 'b' then
a-b = 7 and a+b = 33
a-b+a+b = 7+33
2a = 40
a = 20
Now, 20 - b = 7
-b = -13
b = 13
