Identify which of the following systems of equations has no solution.

\begin{aligned} y & = 10 - 2 x \\ y & = 5 - 2 x \end{aligned}

\begin{aligned} y & = 10 - 2 x \\ 2 y & = 20 - 4 x \end{aligned}

\begin{aligned} y & = 10 - 2 x \\ - y & = 5 - 2 x \end{aligned}

\begin{aligned} y & = 10 - 2 x \\ 3 y & = 30 - 6 x \end{aligned}
