Hi!

J'onn J'onnz worked 7 more problems than Clark Kent. Together they worked 55 problems. How many did each boy work?

I got 31 for J'onn and 24 for Clark:

J'onn = J

Clark = C

J = 7 + C

7 + C = 55

C = 48

48/2 = 24 ==> Clark

24 + 7 = 31 ==> J'onn

Another way is: 55 + 7 = 62

62/2 = 31

31 - 7 = 24

I think my methods are flawed and that's the reason for my seeking help.
