In five bags, there are a total of 100 walnuts. The first two bags together have 52, the second and third bags together have 43, the third and fourth bags together have 34, while the last two bags together contain 30 walnuts. How many walnuts are in each of the bags?
The second and third, fourth and fifth bags together contain $43+30=73$ sunflower seeds. Since the five bags together contain 100 sunflower seeds, there are 27 seeds in the first bag. Thus, the second bag has $52-27=25$, the third bag has $43-25=18$, the fourth bag has $34-18=16$, and the last bag has $30-16=14$ seeds.

With this, we have solved the problem.

Note: Many solvers unnecessarily set up long equations. This problem can be solved with simple logical reasoning, and using a system of five equations is overly complicated.
