# There are real solutions? Can $y$ and $x$ be real numbers? Does this system have solutions? Chemical reaction S+E=SE=P+E Note by Raffaele Piccirillo

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.

Woah. What were you trying to solve?

Modelling an enzimatic reaction :)

Using? A variation of Michelis-Menten?

- 5 years, 4 months ago

Yes =) stating the rate of conversion x in different way :)

- 5 years, 4 months ago

Haha woah cool! I knew it would be that :P
What about approximations? If you assume some concentrations/rate constants are much larger than others, then you can neglect many terms. But I'm sure you've thought about this already.

this is already the reducted model :) but the two therms can't be calculated so easy by my pc xD

- 5 years, 4 months ago

Are x and y concentrations?
If so, then there must be some real solution, right? (as we're modelling a real-world chemical reaction.)

- 5 years, 4 months ago

0<y<1 and 0<x<0.1; y is a constant;x is the inverse of a time =)

Ah okay, now I'm seeing the problem. I can't really help you much more though - have you tried Mathematica Online?

- 5 years, 4 months ago

Not yet,I don't know the website :)

- 5 years, 4 months ago

Oh sure, here it is. There's a fifteen day free trial, which should be enough for your computations.

Thank you =)
