$$\frac{14x}{7y}=2\sqrt{w+19}$$The given equation relates the distinct positive real numbers $w$, $x$, and $y$. Which equation correctly expresses $w$ in terms of $x$ and $y$?

Difficulty: Hard

w=\sqrt{\frac{x}{y}}-19

w=\sqrt{\frac{28x}{14y}}-19

w=\left(\frac{x}{y}\right)^{2}-19

w=\left(\frac{28x}{14y}\right)^{2}-19
