Hi Gmat_mission.

Let's rewrite the given expression as follows: $$n+n=n\cdot n$$ $$2n=n^2$$ $$n^2-2n=0$$ $$n\left(n-2\right)=0$$ Hence, the given equation is true when \(n=0\) and when \(n=2\).

So, there are two integers that satisfy the given equation. Hence, the correct answer is the option [spoiler]C) Two[/spoiler].

I hope it helps you. <i class="em em---1"></i>

Solving the equation, we have:

2n = n^2

n^2 - 2n = 0

n(n - 2) = 0

n = 0 or n = 2

Answer: C
