Let's call Andy 'a' and Jack 'j'.
We know that
a = j +14
and also that
a + j = 56
so we can sub the first equation into the second.
(j +14) + j = 56
2j + 14 = 56
2j = 42
j = 21
Now that we have a value for j, we can sub this back into the first equation.
a = 21 + 14
a = 35
So Jack has 21 and Andy has 35.
I wonder what it is they have...

Combining equal groups together is possible through the concept of multiplication.

Who's a better partner for Jack Shephard Juliet Burke or Kate Austin?
Juliet. They are kindred souls. Both doctors, they understand each other. Kate and Jack never understand each other, never talk about anything together, hide things from each other, keep secrets, never do anything fun together, and Jack's superiority issue is demeaning for Kate. She cries and grovels around him. He is verbally abusive to her. That is not a relationship anywoman should be in.
