Hi everyone again. These problems are tough... I need help... ¡Necesito Ayuda! ;)

In electrical theory, Ohm's law states that

, where

is the current in amperes,

is the electromotive force in volts, and

is the resistance in Ohms.

In a certain circuit V = 110 and R = 50. If V and R are to be changed by the same numerical amount, what change in them will cause

to double?

First I thought it would be imperative to find the new doubled amount.

So currently we have:

Double that would be

I don't see how to make an equation to increase both the V and R by a constant number. Please help and thanks everyone.
