Something simple I forgot how to do

Something simple I forgot how to do! :(

Hello!

For the life of me, I can't remember how to do this! I tried figuring it out from an example, but with no joy.

I need to solve for V_i.

(V_i - 0.58) = (4.42 - V_i).

I'm sure if I just played around with number I could find them, but I want to know the correct way to do it ...so, if anyone could point me in the right direction, I would be forever in your debt!

Thanks in advance.

Your equation can be written more simply, without the parentheses and without the subscripts, as
V - 0.58 = 4.42 - V.

Add V to both sides, and then it should be obvious what to do next.

Ahh of course!

I don't know why I didn't see that!

Again, many thanks.
