# There are real solutions?

Can $y$ and $x$ be real numbers? Does this system have solutions? Chemical reaction S+E=SE=P+E

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.

Woah. What were you trying to solve?

Using? A variation of Michelis-Menten?

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

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

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

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?

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

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