Identify which of the following systems of equations has infinitely many solutions.

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

\begin{aligned} x - y & = 5 \\ 3 x - 3 y & = 10 \end{aligned}

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

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