Hi
I would like to solve a simple equation to two variables.
This is obvious a very simple task for the attached example but as you could imagine, i would like to do the same with much more complex equations.
So my question is, is it possible to solve such an equation to a fraqtion which consists of two variables?
I have tried with solve(...,[x/b]) but i got only an empty result.
If the prime is not able to do so, is there any othe tool out there who can do such a algebraic operation?
Thanks

Hi,
you have to use the CAS ambient in order to do that

Thanks for your answers.
But its not what i have searched for ^^.
The problem is, that in my case, the "a"-part is not that simple.
I think i must give you the real example.
This is my equation:
((r1*r3*u2+r2*r3*u1)/(c2*p*r1*r2*r3+r1*r2+r1*r3+r2*r3)) = (-u2*p*c1*r3)
I want to know what u2/u1 is.
Therefore i have tried to do this:
solve(((r1*r3*u2+r2*r3*u1)/(c2*p*r1*r2*r3+r1*r2+r1*r3+r2*r3)) = (-u2*p*c1*r3),[u2/u1])
but it does not work

but it does not work
I got it … I think the argument has to be a variable name …

Replace u2 with u1*x and solve for x.
Thank you very much!
I think i got it
I love the HP-Forum.
And i love my HP-Calc.
He is much better than my old TI-NSpire. ^^
