Just want to ask if I have an equation $cost = (($q * 5)/$z - $x) * $q *2.32 + 0.34
If $cost, $z and $x
have the actual value, is there any method to calculate $q
without rearranging the eqaution?
Or How to get the new function of $q
in terms of the $cost
?

You want the equation for `$q`? That would be a different equation, and by definition you need to rearrange this one. Have I misunderstood what you're asking? – xXhRQ8sD2L7Z Nov 15 '16 at 22:51

Sounds like you need to review your algebra. – Bill_Stewart Nov 15 '16 at 23:05

@ST8Z6FR57ABE6A8RE9UF To solve this equation, yes, normally we do need to rearrange the equation. But I just want to know if there is any method to solve the equation without rearranging it. Sometimes it will be difficult to rearrange a very complex equation manually. – rock Nov 15 '16 at 23:08

@Bill_Stewart Well, if there is a method to automatically look for the solution, it will save a lot of time when you have more than 100 eqautions to solve. – rock Nov 15 '16 at 23:10

Sometimes you need to use the right tool for the right job. I suggest Wolfram Alpha to solve these types of problems. https://www.wolframalpha.com/ – Knox Nov 15 '16 at 23:37

@Knox Thanks for the tool. I am just curious if there is any function could do the same work. – rock Nov 16 '16 at 02:34

possibler with dichotomie method i think – Esperento57 Nov 16 '16 at 07:02
