Tension on a rope is being pulled by two kids

What's the tension on a rope is being pulled by two kids with the same force on each side >>>
What if the forces on each side are different ?

I think the tension on the rope is equal to the sum of the forces acted by the kids
why ?? just like this I can't explain it??

Think about this: What if instead of being pulled by two kids, the rope had one end tied to a hook in the wall and the other end pulled by one kid (with the same force as before). Would the tension be any different?
