Gary knows that \(\text{p} = 2\cfrac{1}{2}\) is a solution to one of the following equations. Which one has \(\text{p} = 2\cfrac{1}{2}\) as its solution?

\(\text{p} + 2\cfrac{1}{2} = 5\)          \(\text{p} - 2\cfrac{1}{2} = 5\) 

\(2 + \text{p} = 2\cfrac{1}{2}\)          \(4 - \text{p} = 2\cfrac{1}{2}\)
