This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.

Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

You should begin by telling us what you have tried.

What have you tried? Where did you get stuck?

Simply demanding that others "do for me" isn't being respectful of them.

Why would you expect there to be a "nicer" answer?

Are you sure you want real solutions instead of just integer solutions?

It's like saying "The original problem is solve for $x = 1, y = 2$. I'm going to ask them to solve $x+y = 3$."

E.g. I tried to combine all 4 equations. The larger equation cannot be easily solved. There seem to be a lot of solutions to this equation.
