Another set of two bricks weighs 26 pounds. The final set of two bricks weighs 30 pounds. How much does each brick weigh?

First, we need to use one common brick weight. That will be 16. So one brick needs to be 10 and another 14. 14 plus 16 is 30, 10 plus 16 is 26, and 10 plus 14 is 24.

So the three bricks are 10,14, and 16 pounds.
