Find the values of a real parameter
\(t\) which
ensure that the following system has a unique solution.
\[ \begin{alignedat}{80}
tx & + &y & + &3 & = 0 & & & & & &
\\4x & - 2 &y & + &1 & = 0 & & & & & &
\\\end{alignedat}\]
\(t\in \mathbb{R}\setminus \{ - 2\}\)
\(t\in \mathbb{R}\)
\(t = -2\)
\(t\in \emptyset \)
