What is the value of n^2/(x + n)?

(1) n^2 – 5n – 4x = x

(2) x = n

Statement 1: \(n^2 = x+4x+5n = 5(x+n)\). We can substitute the value of \(n^2\) to get the value of the expression. Hence

SufficientStatement 2: \(x=n\). on substituting the value of \(x\) in the expression \(\frac{n^2}{(n+n)} = \frac{n}{2}\). But we don't know the value of \(n\). Hence
