a + b = 49
a - b = 9
Add both together to get
(a+a)+(b-b) = 58
2a=58
a = 29 ◄
plug that into the second equation to get
29 - b = 9
so b = 20 ◄
Check:
29 + 20 = 49
29 - 20 = 9
19 and 34
20 & 3

12 and 24?
18 and -6.
22 and 26
29 and 36

12 and 24?
18 and -6.
38-4=34
The answer is 39 and 19 (: hope this helps!
That's not possible... * * * * * How about -5 and 25?
