Need help rearranging an equation in physics?V= [1/4??] [Q/R]?
an some one show me how to rearrange and solve for Q

V= [1/4??] [Q/R]

this is an eletric voltage equation and i need to solve for Q can some one go through it slowly for me please thanks

First you can multiply everything out, i.e the the denominator by the denominator and the numerator by the numerator :

V = (Q)/(4R??)

Remember from algebra or whenever that:

in order to get remove x from 2/x you need to multiply by x: (2/x)*(x) = 2/1 = 2

Since you are solving for Q, you need to get Q by itself, i.e. to Q/1 = Q

you will need to multiply by 4R?? to get Q by itself. Remember that whatever you do to one side of = you have to do it to the other side.

V*4R?? = (4R??*Q)/(4R??)

Q/1 = V*4R??
Q = 4VR??
