Solving Equations for C: A Guide for Physics Beginners

[ronislegend]

Hey in my Physics class which just started, there's these 3 problems I do not know how to do. If someone could assist me and or show me the correct way how to do these... Now I know a little bit about how about going this but I just can't seem to solve them. I'm sorry if this is a n00b physics question. My first day in "Honors Physics";

It goes like this: "Rearrange the equations so they solve for the variable "C". SHOW WORK"

BCA/R=V


C-B/A=VR


VB/R=A+C^2

This is just basic algebra. You can do (nearly) any operation to both sides of an equation, and the equation will remain true. For example, you can divide both sides of your first equation by B, and you'll end up with

CA/R = V/B

which is closer to your desired solution.

Thank you, I understand now!

Hey does "chroot" mean your a linux guru?

 

[chroot]

Something like that, yes.
