For problem 7.25, it is clear that the two situations produce the same outcomes, but what exactly does it mean when it tells us to "write out the bijection" ? Do we need to write out a function or something of that sort, or do we just explain why the two situations lead to the same outcomes ? Thank you !

Here you just need to say which solution to the equation would a certain arrangement of the balls in the boxes would correspond to.

Note it is not enough to know that there are the same number of each, but we have to specifically say which arrangement of balls corresponds to which solution to the equation.
